	First step in trying to make menu.c cleaner: move the panel context
	menu in a new file

	* Makefile.am: add new files
	* menu.[ch]: (menu_get_panel), (menuitem_to_screen),
	(add_menu_separator): these functions are no longer static
	(check_for_screen), (show_about_dialog), (about_gnome_cb),
	(create_new_panel), (remove_panel), (setup_remove_this_panel),
	(make_panel_submenu), (show_panel_help), (create_panel_context_menu):
	move these functions...
	* panel-context-menu.[ch]: ... here (new files)
	* panel.c: (panel_menu_get): updated
