Allow menu to refresh

[puzzledmonkey]

In several cases an action a user performs might update their menu (due to new access being given, or other changes that change the canSee or canSeeWhen values). The primary places this might happen are after an action runs, or when creating/updating/deleting/etc a resource.

It would be great to have a refreshesMenu() { return true; } function or $refreshesMenu = true; property to allow us to mark resources and actions as requiring a menu refresh after resource create/update/delete/restore or action runs.
