Paul Fitzpatrick	3d3fe92bd0	(core) support access control on columns ... Summary: Adds a granular access clause for columns. Permissions can be specified for a set of columns within a table. Permissions accumulate over clauses, in a way that is intended as a placeholder pending final design. Test Plan: Added tests. Tested manually that updates to private columns are not sent to people who don't have access to them. There are a lot of extra tests needed and TODOs to be paid down after this experimental phase.

Paul Fitzpatrick	c879393a8e	(core) support adding user characteristic tables for granular ACLs ... Summary: This is a prototype for expanding the conditions that can be used in granular ACLs. When processing ACLs, the following variables (called "characteristics") are now available in conditions: * UserID * Email * Name * Access (owners, editors, viewers) The set of variables can be expanded by adding a "characteristic" clause. This is a clause which specifies: * A tableId * The name of an existing characteristic * A colId The effect of the clause is to expand the available characteristics with all the columns in the table, with values taken from the record where there is a match between the specified characteristic and the specified column. Existing clauses are generalized somewhat to demonstrate and test the use these variables. That isn't the main point of this diff though, and I propose to leave generalizing+systematizing those clauses for a future diff. Issues I'm not dealing with here: * How clauses combine. (The scope on GranularAccessRowClause is a hack to save me worrying about that yet). * The full set of matching methods we'll allow. * Refreshing row access in clients when the tables mentioned in characteristic tables change. * Full CRUD permission control. * Default rules (part of combination). * Reporting errors in access rules. That said, with this diff it is possible to e.g. assign a City to editors by their email address or name, and have only rows for those Cities be visible in their client. Ability to modify those rows, and remain updates about them, remains under incomplete control.

Paul Fitzpatrick	a4929bde72	(core) add some row-level access control ... Summary: This implements a form of row-level access control where for a given table, you may specify that only owners have access to rows for which a given column has falsy values. For simplicity: * Only owners may edit that table. * Non-owners with the document open will have forced reloads whenever the table is modified. Baby steps...
