Add support for installing missing GTK+ theme engines via packagekit (bug

Browse source 
2008-05-07  Jens Granseuer  <jensgr@gmx.net>

	Add support for installing missing GTK+ theme engines via
	packagekit (bug #511065)

	* appearance-themes.c: (theme_message_area_response_cb),
	(theme_message_area_update): when we detect a missing engine,
	check if packagekit is available on the session bus. If it is show
	an install button to pull the corresponding package
	* appearance.h:
	* theme-util.c: (packagekit_available), (theme_install_file):
	* theme-util.h: add support functions
