	Migrate to GtkTooltip.

	* panel-util.[ch]: (panel_util_query_tooltip_cb): new, check if
	tooltips are enabled but displaying one
	(panel_util_set_tooltip_text): wrapper for tooltip for the panel,
	since we need to check if the tooltips are enabled in the panel config.
	* panel-config-global.c: simplify, since we don't need to do the
	GtkTooltips stuff
	* main.c: (main):
	* panel-globals.h: remove useless global GtkTooltips variable
	* drawer.c:
	* launcher.c:
	* menu.c:
	* panel-action-button.c:
	* panel-menu-button.c:
	* panel-menu-items.c:
	* panel-recent.c: use panel_util_set_tooltip_text()
	* panel-menu-bar.c: (panel_menu_bar_enter_applications): kill
	(panel_menu_bar_enter_places): kill
	(panel_menu_bar_enter_desktop): kill
	(panel_menu_bar_reinit_tooltip): updated
	(panel_menu_bar_hide_tooltip): updated
	(panel_menu_bar_setup_tooltip): simplify thanks to GtkTooltip
	* gnome-desktop-item-edit.c:
	(panel_global_config_get_tooltips_enabled): needed symbol for
	compilation. This is just a hacky workaround.
