Summary:
- Support schema changes in the presence of non-trivial ACL rules.
- Fix update of `aclFormulaParsed` when updating formulas automatically after schema change.
- Filter private metadata in broadcasts, not just fetches. Censorship method is unchanged, just refactored.
- Allow only owners to change ACL rules.
- Force reloads if rules are changed.
- Track rule changes within bundle, for clarity during schema changes - tableId and colId changes create a muddle otherwise.
- Show or forbid pages dynamically depending on user's access to its sections. Logic unchanged, just no longer requires reload.
- Fix calculation of pre-existing rows touched by a bundle, in the presence of schema changes.
- Gray out acl page for non-owners.
