(core) discount indirect changes for access control purposes

Summary:
This diff discounts indirect changes for access control purposes.  A UserAction that updates a cell A, which in turn causes changes in other dependent cells, will be considered a change to cell A for access control purposes.

The `engine.apply_user_actions` method now returns a `direct` array, with a boolean for each `stored` action, set to `true` if the action is attributed to the user or `false` if it is attributed to the engine.  `GranularAccess` ignores actions attributed to the engine when checking for edit rights.

Subtleties:
 * Removal of references to a removed row are considered direct changes.
 * Doesn't play well with undos as yet.  An action that indirectly modifies a cell the user doesn't have rights to may succeed, but it will not be reversible.

Test Plan: added tests, updated tests
