Rework the way the color scheme setting is inherited. Now the overriding

	* gtk/gtksettings.[hc]: Rework the way the color scheme setting
	is inherited. Now the overriding is done on a per-color basis,
	rather than for the setting as a whole. This has the effect
	that themes can declare defaults for all the symbolic colors they
	use by specifying a value for the gtk-color-scheme setting in
	their rc file, while still allowing the XSetting to override
	"standard" symbolic colors. The hash table is now available
	through the color-hash property.

	* gtk/gtkrc.c: Use the new color-hash property.
