	* gedit-window.c:
	* gedit-app.[ch]:

	properly use window::dispose to drop the references to the ui
	manager and to disconnect the recents_changed callback. It
should
	fix warning and crashes. Also turn the lockdown changed handler
	in a simple method so that we avoid headaches tracking the
lifetime
	of the window itself.
