Summary:
* Adds a `SELF_HYPERLINK()` python function, with optional keyword arguments to set a label, the page, and link parameters.
* Adds a `UUID()` python function, since using python's uuid.uuidv4 hits a problem accessing /dev/urandom in the sandbox. UUID makes no particular quality claims since it doesn't use an audited implementation. A difficult to guess code is convenient for some use cases that `SELF_HYPERLINK()` enables.
The canonical URL for a document is mutable, but older versions generally forward. So for implementation simplicity the document url is passed it on sandbox creation and remains fixed throughout the lifetime of the sandbox. This could and should be improved in future.
The URL is passed into the sandbox as a `DOC_URL` environment variable.
The code for creating the URL is factored out of `Notifier.ts`. Since the url is a function of the organization as well as the document, some rejiggering is needed to make that information available to DocManager.
On document imports, the new document is registered in the database slightly earlier now, in order to keep the procedure for constructing the URL in different starting conditions more homogeneous.

- Fix update of `aclFormulaParsed` when updating formulas automatically after schema change.
- Filter private metadata in broadcasts, not just fetches. Censorship method is unchanged, just refactored.
- Allow only owners to change ACL rules.
- Force reloads if rules are changed.
- Track rule changes within bundle, for clarity during schema changes - tableId and colId changes create a muddle otherwise.
- Show or forbid pages dynamically depending on user's access to its sections. Logic unchanged, just no longer requires reload.
- Fix calculation of pre-existing rows touched by a bundle, in the presence of schema changes.

Summary:
With this change, if a comment is added to an ACL formula, then that comment will be offered to the user if access is denied and that rule could potentially have granted access.
The code is factored so that when access is permitted, or when partially visible tables are being filtered, there is little overhead. Comments are gathered only when an explicit denial of access.

Summary:
An incorrect DocAction (as possible from an Undo of a non-last action)
could cause RemoveRecord on an already missing record. This used to
create an invalid undo, and wreak havoc when a series of DocActions
later fails and needs to be reverted.
To fix, consider RemoveRecord of a missing record to be a no-op.
Test Plan: Includes a new test case that triggers the problem.

Summary:
Currently, an undo of a non-last action can leave the doc in an inconsistent
state. For example, it may remove a table, but fail to remove all columns of
it from metadata. We normally check that schema corresponds to metadata, but
stray columns were not visible to this check, and instead caused later table
additions to fail.
This diff fixes the check to fail the action that causes stray columns, and
to restore the doc to a consistent state.
Note that this only handles schema-metadata inconsistencies, but an undo of a
non-last action can easily create other surprises.
Test Plan: Added a test case that triggered inconsistency before, and now triggers a failed undo.

Summary:
- Placed rule-updating functions in acl.py.
- Reset UI when rules update externally, or alert the user to reset if there
are pending local changes.
- Removed some unused and distracting bits from client-side DocModel.
A few improvements related to poor error handling:
- In case of missing DocActions (tickled by broken ACL rule handling), don't
add to confusion by attempting to process bad actions
- In case of missing attributes in ACL formulas, return undefined rather than
fail; the latter creates more problems.
- In case in invalid rules, fail rather than skip; this feels more correct now
that we have error checking and recovery option, and helps avoid invalid rules.
- Prevent saving invalid rules with an empty ACL formula.
- Fix bug with rule positions.

Summary:
- Introduce a new SQLiteDB migration, which adds DB columns for formula columns
- Newly added columns have the special ['P'] (pending) value in them
(in order to show the usual "Loading..." on the first load that triggers the migration)
- Calculated values are added to .stored/.undo fields of user actions.
- Various changes made in the sandbox to include .stored/.undo in the right order.
- OnDemand tables ignore stored formula columns, replacing them with special SQL as before
- In particular, converting to OnDemand table leaves stale values in those
columns, we should maybe clean those out.
Some tweaks on the side:
- Allow overriding chai assertion truncateThreshold with CHAI_TRUNCATE_THRESHOLD
- Rebuild python automatically in watch mode

Summary:
This makes it possible to serve a table or tables only to owners.
* The _grist_ACLResources table is abused (temporarily) such that rows of the form `{colId: '~o', tableId}` are interpreted as meaning that `tableId` is private to owners.
* Many websocket and api endpoints are updated to preserve the privacy of these tables.
* In a document where some tables are private, a lot of capabilities are turned off for non-owners to avoid leaking info indirectly.
* The client is tweaked minimally, to show '-' where a page with some private material would otherwise go.
No attempt is made to protect data from private tables pulled into non-private tables via formulas.
There are some known leaks remaining:
* Changes to the schema of private tables are still broadcast to all clients (fixable).
* Non-owner may be able to access snapshots or make forks or use other corners of API (fixable).
* Changing name of table makes it public, since tableId in ACLResource is not updated (fixable).
Security will require some work, the attack surface is large.
