Make the location entry an EggToolItem, and provide a custom tooptip

2003-07-01  Christian Persch  <chpe@cvs.gnome.org>

	* lib/widgets/ephy-location-entry.h:
	* lib/widgets/ephy-location-entry.c: (ephy_location_entry_set_tooltip),
	(ephy_location_entry_construct_contents),
	(ephy_location_entry_class_init), (ephy_location_entry_init),
	(ephy_location_entry_finalize):

	Make the location entry an EggToolItem, and provide a custom
	tooptip setter. Fix mem leak.

	* src/ephy-location-action.c: (create_tool_item),
	(ephy_location_action_class_init), (connect_proxy):

 	Use the location entry EggToolItem instead of constructing it
 	explicitly.

 	* src/toolbar.c: (toolbar_setup_action):

 	Set tooltip for location entry.

 	* lib/egg/egg-action.c: (connect_proxy), (disconnect_proxy):

 	Connect the tooltip sync'er on any EggToolItem, not just EggTollButton:s.
 	Disconnect the tooltip sync func on disconnect, too.
