	Support subclasses in RC files.  (#142417, Todd Berman, patch
	based on a patch by Benjamin Berg)

	* gtk/gtkrc.h:
	* gtk/gtkrc.c: Support <classname> elements in widget_class paths
	in rc files which match any classes derived from named class.

	(_gtk_rc_init): Use the new syntax in the default rc string.

	* gtk/gtkbindings.c: Support the new syntax for bindings too.

	* tests/testrc.c: Tests for widget_class path matching
