b416a5c4b1 (core) Fix error when updating summary table formulas after rename
Summary:
Formulas in summary tables were being associated with the source table for automatic updating. When a table/column was renamed such that the formula needed to update to match, it would look for a column with the same colId but in the source table. Such a column might not exist which would lead to an error, or if it existed then the update would be wrong.

This association was created while building formulas to display in the code view in a nested `_Summary` class, it didn't need to exist at all. So this diff simply prevents the association from being created.

Test Plan: Extended `TestSummary.test_table_rename` Python test.

b8486dcdba (core) Nice summary table IDs
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.

Test Plan:
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.

Added a test for the migration, including renames in formulas.

e5eeb3ec80 (core) Add 'user' variable to trigger formulas
Summary:
The 'user' variable has a similar API to the one from access rules: it
contains properties about a user, such as their full name and email
address, as well as optional, user-defined attributes that are populated
via user attribute tables.

Test Plan: Python unit tests.

8524b4f791 (core) Put user code in linecache so that source lines show in tracebacks
Summary: See title. This should improve the user experience, but more importantly it's something I've wanted several times when developing (including just now) so I've been meaning to do this.

a56714e1ab (core) Implement trigger formulas (generalizing default formulas)
Summary:
Trigger formulas can be calculated for new records, or for new records and
updates to certain fields, or all fields. They do not recalculate on open,
and they MAY be set directly by the user, including for data-cleaning.

- Column metadata now includes recalcWhen and recalcDeps fields.
- Trigger formulas are NOT recalculated on open or on schema changes.
- When recalcWhen is "never", formula isn't calculated even for new records.
- When recalcWhen is "allupdates", formula is calculated for new records and
  any manual (non-formula) updates to the record.
- When recalcWhen is "", formula is calculated for new records, and changes to
  recalcDeps fields (which may be formula fields or column itself).
- A column whose recalcDeps includes itself is a "data-cleaning" column; a
  value set by the user will still trigger the formula.
- All trigger-formulas receive a "value" argument (to support the case above).

Small changes
- Update RefLists (used for recalcDeps) when target rows are deleted.
- Add RecordList.__contains__ (for `rec in refList` or `id in refList` checks)
- Clarify that Calculate action has replaced load_done() in practice,
  and use it in tests too, to better match reality.

Left for later:
- UI for setting recalcWhen / recalcDeps.
- Implementation of actions such as "Recalculate for all cells".
- Allowing trigger-formulas access to the current user's info.

Test Plan: Added a comprehensive python-side test for various trigger combinations
