* Simple and consistent interface for marking a snippet subclass as editable by admins only: set the _adminOnly property of the manager object to true
* Compatible with new submit-*, edit-* permissions on a per-type basis
* aposSnippetMenu and friends now expect to be passed the permissions object, and JUST that (no wrapper object needed). Also still supports an explicit "edit: true" but you won't get the import option that way, so please just upgrade your outerLayout to this simpler and better approach. This applies ONLY to snippet-derived modules, nothing has changed re aposPagesMenu and aposMediaMenu
* If the user only has the new submit-* permission for the type, never let them publish it themselves, and also invoke self.publishBlocked which can be overridden to set further flags by the apostrophe-moderator module
