0c80547e0d (core) Change UndoStack._linkMap to store an array of action groups for each linkId
Summary:
While working on type conversion, I ran into a bug when multiple action groups belonging to a bundle are quickly sent. `DocData._sendActionsImpl` can set the same `linkId: this._lastActionNum` on multiple action groups before `_lastActionNum` is updated with a result from the server. Only one of these groups gets saved in `UndoStack._linkMap` so undoing a bundle misses out on some action groups.

This diff associates each `linkId` key with an array of action groups instead of just one, then combines them all together when undoing.

Test Plan: I've confirmed that this fixes my problem within my type conversion diff, but I haven't found a way to reproduce the general problem in master. I think the existing tests are probably fine since undo is tested extensively everywhere, but I'd also like to see if there are existing bugs which this fixes.

876a0298a2 (core) do not look at content of recent actions when loading documents
Summary:
This removes the need for any information drawn from the content of recent actions when loading a document.

The undo/redo system does need some facts about recent actions up front. But that system has an important restriction: only actions a particular client is known to have generated can be undone by that client.

So in this diff, as we store which client has performed an action, we also store the few pieces of metadata about that action that the undo/redo system needs: `linkId`, `otherId`, `rowIdHint`, `isUndo` fields. These are all small integers (or in one case a boolean).

An existing limitation is that information about which client has performed which action is stored in memory in the worker, and not persisted anywhere. This diff does not change that limitation, meaning that undos continue to not survive a worker transition. A reasonable way to deal with that would be to back the store with redis.

Test Plan: existing tests pass

d1c1416d78 (core) Add rules to eslint to better match our coding conventions.
Summary:
We used tslint earlier, and on switching to eslint, some rules were not
transfered. This moves more rules over, for consistent conventions or helpful
warnings.

- Name private members with a leading underscore.
- Prefer interface over a type alias.
- Use consistent spacing around ':' in type annotations.
- Use consistent spacing around braces of code blocks.
- Use semicolons consistently at the ends of statements.
- Use braces around even one-liner blocks, like conditionals and loops.
- Warn about shadowed variables.

Test Plan: Fixed all new warnings. Should be no behavior changes in code.

1654a2681f (core) move client code to core
Summary:
This moves all client code to core, and makes minimal fix-ups to
get grist and grist-core to compile correctly.  The client works
in core, but I'm leaving clean-up around the build and bundles to
follow-up.

Test Plan: existing tests pass; server-dev bundle looks sane
