GtkMenuTrackerItem: add support for dynamic accels

Browse Source 
Add support for pulling the primary accel out of the GtkActionMuxer.

With this change, it is no longer necessary to have the accel=''
attribute hardcoded onto each menu item (and, in fact, it should be left
off if you intend to have support for dynamic accelerator changing).

Specifying accel='' is a good way to force an accelerator not to be
displayed on a menu item.
