Create module::event() which runs Gallery events. It works by

convention.  To respond to the "photo_created" event in the gmaps
module, you create modules/gmaps/helpers/gmaps_event.php containing
class gmaps_event which has function photo_created.

Renamed all events from gallery.foo.bar to foo_bar
Updated tag module to use new convention.
