Handle setting the search bar to "Advanced..." when the alphabet buttons

2002-01-11  Christopher James Lahey  <clahey@ximian.com>

	* gui/component/addressbook.c (alphabet_state_changed): Handle
	setting the search bar to "Advanced..." when the alphabet buttons
	are pushed and back when they're cleared.  Fixes Ximian bug
	#12904.
	(addressbook_menu_activated): When the user calls Search->clear,
	set the search to ESB_ANY and "", don't just set the text.  This
	is especially useful when it's set to ESB_ADVANCED.

	* gui/widgets/e-addressbook-view.c,
	gui/widgets/e-addressbook-view.h (alphabet_state_change): Added
	this signal which gets emitted when the alphabet buttons are
	pushed.
	(command_state_change): Removed the ref pair here.  It's not
	necessary.  gtk_signal_emit refs the object itself.
