Allow the user to select a different bookmark topic on the toolbar by just

2007-04-02  Diego Escalante Urrelo <diegoe@gnome.org>

	* src/bookmarks/ephy-topic-action.c:

	Allow the user to select a different bookmark topic on the toolbar by
	just moving the mouse. Old behaviour forced the user to click each
	topic button to activate the menu, now only the first click is
	required. Bug #363848. Patch by John Millikin.
