	* gtk/gtksearchenginequartz.[ch]: Add a search engine which queries
	the Spotlight database on MacOS X (only available in 10.4 and
	higher).

	* gtk/gtksearchengine.c (_gtk_search_engine_new): try creating
	quartz search engine if we are on OS X.

	* Makefile.am: added use_quartz_sources section with new file.
