* Remove the user_event callbacks and move them to the gallery_event callbacks. This will insure that the active user is always loaded (because the gallery callbacks are always called first) to its available to other gallery_ready handlers. Moved the method set_request_locale to the locales helper as it is more related to locales.
* Move the user controllers and views into the gallery module.
* Move the theme and block processing out of the user module and into core.
* Refactor gallery.php to move site_menu, admin_menu, and context_menu to gallery_event.php
* Change Theme_View and Admin_view to call module::event("site_menu|admin_menu|context_menu"...)
1) The item_updated event no longer takes the old and new items.
Instead we overload ORM to track the original data and make
that available via the item. This will allow us to move event
publishing down into the API methods which in turn will give us
more stability since we won't require each controller to remember
to do it.
2) ORM class now tracks the original values. It doesn't track
the original relationships (no need for that, yet)
3) Added new events:
item_deleted
group_deleted
user_deleted
