Summary:
Attachments are a special case for granular access control. A user is now allowed to read a given attachment if they have read access to a cell containing its id. So when a user writes to a cell in an attachment column, it is important that they can only write the ids of cells to which they have access. This diff allows a user to add an attachment id in a cell if:
* The user already has access to that a attachment via some existing cell, or
* The user recently updated the attachment, or
* The attachment change is from an undo/redo of a previous action attributed to that user

- Comments are stored in a generic metatable `_grist_Cells`
- Each comment is connected to a particular cell (hence the generic name of the table)
- Access level works naturally for records stored in this table
-- User can add/read comments for cells he can see
-- User can't update/remove comments that he doesn't own, but he can delete them by removing cells (rows/columns)
-- Anonymous users can't see comments at all.
- Each comment can have replies (but replies can't have more replies)
Comments are hidden by default, they can be enabled by COMMENTS=true env variable.

This makes two small tweaks based on a user's questions about sharing
sites publicly for a self-managed installation:
* The support user `support@getgrist.com` is made configurable with
`GRIST_SUPPORT_EMAIL`. This came up because only the support user
can share material with the special "everyone" user. This restriction
was added to avoid spam.
* Regardless of public sharing settings, for our SaaS we had
decided not to list public sites to anonymous users. That is
somewhat a question of taste, so a `GRIST_LIST_PUBLIC_SITES` flag
is added to override this choice.

Summary:
This diff adds a preview of the value of certain autocomplete suggestions, especially of the form `$foo.bar` or `user.email`. The main initial motivation was to show the difference between `$Ref` and `$Ref.DisplayCol`, but the feature is more general.
The client now sends the row ID of the row being edited (along with the table and column IDs which were already sent) to the server to fetch autocomplete suggestions. The returned suggestions are now tuples `(suggestion, example_value)` where `example_value` is a string or null. The example value is simply obtained by evaluating (in a controlled way) the suggestion in the context of the given record and the current user. The string representation is similar to the standard `repr` but dates and datetimes are formatted, and the whole thing is truncated for efficiency.
The example values are shown in the autocomplete popup separated from the actual suggestion by a number of spaces calculated to:
1. Clearly separate the suggestion from the values
2. Left-align the example values in most cases
3. Avoid having so much space such that connecting suggestions and values becomes visually difficult.
The tokenization of the row is then tweaked to show the example in light grey to deemphasise it.
Main discussion where the above was decided: https://grist.slack.com/archives/CDHABLZJT/p1661795588100009
The diff also includes various other small improvements and fixes:
- The autocomplete popup is much wider to make room for long suggestions, particularly lookups, as pointed out in https://phab.getgrist.com/D3580#inline-41007. The wide popup is the reason a fancy solution was needed to position the example values. I didn't see a way to dynamically resize the popup based on suggestions, and it didn't seem like a good idea to try.
- The `grist` and `python` labels previously shown on the right are removed. They were not helpful (https://grist.slack.com/archives/CDHABLZJT/p1659697086155179) and would get in the way of the example values.
- Fixed a bug in our custom tokenization that caused function arguments to be weirdly truncated in the middle: https://grist.slack.com/archives/CDHABLZJT/p1661956353699169?thread_ts=1661953258.342739&cid=CDHABLZJT and https://grist.slack.com/archives/C069RUP71/p1659696778991339
- Hide suggestions involving helper columns like `$gristHelper_Display` or `Table.lookupRecords(gristHelper_Display=` (https://grist.slack.com/archives/CDHABLZJT/p1661953258342739). The former has been around for a while and seems to be a mistake. The fix is simply to use `is_visible_column` instead of `is_user_column`. Since the latter is not used anywhere else, and using it in the first place seems like a mistake more than anything else, I've also removed the function to prevent similar mistakes in the future.
- Don't suggest private columns as lookup arguments: https://grist.slack.com/archives/CDHABLZJT/p1662133416652499?thread_ts=1661795588.100009&cid=CDHABLZJT
- Only fetch fresh suggestions specifically after typing `lookupRecords(` or `lookupOne(` rather than just `(`, as this would needlessly hide function suggestions which could still be useful to see the arguments. However this only makes a difference when there are still multiple matching suggestions, otherwise Ace hides them anyway.
Test Plan: Extended and updated several Python and browser tests.

Summary:
This diff adds a new `BulkAddOrUpdateRecord` user action which is what is sounds like:
- A bulk version of the existing `AddOrUpdateRecord` action.
- Much more efficient for operating on many records than applying many individual actions.
- Column values are specified as maps from `colId` to arrays of values as usual.
- Produces bulk versions of `AddRecord` and `UpdateRecord` actions instead of many individual actions.
Examples of users wanting to use something like `AddOrUpdateRecord` with large numbers of records:
- https://grist.slack.com/archives/C0234CPPXPA/p1651789710290879
- https://grist.slack.com/archives/C0234CPPXPA/p1660743493480119

- https://grist.slack.com/archives/C0234CPPXPA/p1663069291726159
I tested what made many `AddOrUpdateRecord` actions slow in the first place. It was almost entirely due to producing many individual `AddRecord` user actions. About half of that time was for processing the resulting `AddRecord` doc actions. Lookups and updates were not a problem. With these changes, the slowness is gone.
The Python user action implementation is more complex but there are no surprises. The JS API now groups `records` based on the keys of `require` and `fields` so that `BulkAddOrUpdateRecord` can be applied to each group.
Test Plan: Update and extend Python and DocApi tests.

Summary:
Changes auto-generated summary table IDs from e.g. `GristSummary_6_Table1` to `Table1_summary_A_B` (meaning `Table1` grouped by `A` and `B`). This makes it easier to write formulas involving summary tables, make API requests, understand logs, etc.
Because these don't encode the source table ID as reliably as before, `decode_summary_table_name` now uses the summary table schema info, not just the summary table ID. Specifically, it looks at the type of the `group` column, which is `RefList:<source table id>`.
Renaming a source table renames the summary table as before, and now renaming a groupby column renames the summary table as well.
Conflicting table names are resolved in the usual way by adding a number at the end, e.g. `Table1_summary_A_B2`. These summary tables are not automatically renamed when the disambiguation is no longer needed.
A new migration renames all summary tables to the new scheme, and updates formulas using summary tables with a simple regex.

Updated many tests to use the new style of name.
Added new Python tests to for resolving conflicts when renaming source tables and groupby columns.

This does not cover:
* Granular write access for attachments. In particular, a user who can write to any attachment column should be considered to have full read access to all attachment columns, currently.
* Access control of attachment metadata such as name and format.
The implementation uses a sql query that requires a scan, and some notes on how this could be optimized in future. The web client was updated to specify the cell to check for access, and performance seemed fine in casual testing on a doc with 1000s of attachments. I'm not sure how performance would hold up as the set of access rules grows as well.

Adds a Python function `REQUEST` which makes an HTTP GET request. Behind the scenes it:
- Raises a special exception to stop trying to evaluate the current cell and just keep the existing value.
- Notes the request arguments which will be returned by `apply_user_actions`.
- Makes the actual request in NodeJS, which sends back the raw response data in a new action `RespondToRequests` which reevaluates the cell(s) that made the request.
- Wraps the response data in a class which mimics the `Response` class of the `requests` library.
In certain cases, this asynchronous flow doesn't work and the sandbox will instead synchronously call an exported JS method:
- When reevaluating a single cell to get a formula error, the request is made synchronously.
- When a formula makes multiple requests, the earlier responses are retrieved synchronously from files which store responses as long as needed to complete evaluating formulas. See https://grist.slack.com/archives/CL1LQ8AT0/p1653399747810139
