Paul Fitzpatrick	0e2deecc55	(core) implement cleaner row-level access control for outgoing messages ... Summary: This implements row-level access control for outgoing messages, replacing the document reloading placeholder that was there before. * Prior to broadcasting messages, GranularAccess is notified of actions+undo. * While broadcasting messages to different sessions, if we find we need row level access control information, rows before and after the change are reconstructed. * Messages are rewritten if rows that were previously forbidden are now allowed, and vice versa. The diff is somewhat under-tested and under-optimized. Next step would be to implement row-level access control for incoming actions, which may result in some rejiggering of the code from this diff to avoid duplication of effort under some conditions.

Paul Fitzpatrick	c387fc4bce	(core) hide long sequences of unchanged rows in diffs ... Summary: It can be hard to find changes, even when highlighted, in a table with many rows. This diff replaces long sequences of unchanged rows with a row containing "..."s. With daff, I found that it is important to do this for sequences of unchanged columns also, but not tackling that yet.

Paul Fitzpatrick	e5b67fee7e	(core) visualize simple differences between documents ... Summary: Render simple differences between documents. * Show cell changes. * Show cell conflicts. * Show row additions/deletions. Doesn't support any schema changes, and is untested in the presence of schema changes. Any widgets that access row data without using `cells` fields won't receive correct data. Not addressed: * Rendering conflicts in mixed row addition/updating/deleting. * Column additions/deletions, option changes, etc. * Document level changes. * Table and column renames (though anticipated in ActionSummary structure). * Page-level changes. * Drawing attention to changes (marking changed pages+views, suppressing unchanged rows, etc). * Rendering differences in views other than GridView. * Adding UI for initiating a comparison. * Editing while comparing.

Paul Fitzpatrick	ac5452c89f	(core) add grist.onRecord and grist.onRecords event handlers ... Summary: This simplifies writing custom widgets that access selected data. To access the record at which the cursor is set, and get any future changes to it as the cursor moves or data changes, it suffices now to do: ``` grist.ready(); grist.onRecord(record => /* render */); ``` Similarly to access the set of selected records, and get any changes, it suffices now to do: ``` grist.ready(); grist.onRecords(records => /* render */); ``` The `records` argument will be a list of objects, each of which is a single record. This is distinct from the column-based representation favored in Grist up ontil now. That remains how methods like `fetchTable` or `fetchSelectedTable` represent their results. In the future, methods named like `fetchRecords` or `fetchSelectedRecords` could be added that return lists.

Paul Fitzpatrick	5ef889addd	(core) move home server into core ... Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
