2001-05-21  Chris Toshok  <toshok@ximian.com>

	* menus/gal-view-menus.c (build_menus): make the view menuitems
	radio items of the same group, and allocate the closure here.
	(free_verbs): only need to free the one DefineViews verb here.
	(closure_free): new function - EListFreeFunc for our
	listenerClosure list.
	(remove_listeners): new function, free our listener list.
	(gvm_destroy): call remove_listeners.
	(gvm_init): init listenerClosures list.
	(toggled_cb): callback for radio items.
	(build_verbs): strip out almost all the code since there's only 1
	verb now.
	(build_stuff): call remove_listeners.
