	* preferences.c: (bg_preferences_load),
	(bg_preferences_merge_entry), (read_wptype_from_string),
	(read_orientation_from_string): Make read_orientation_from_string()
	and read_wptype_from_string() behave like read_color_from_string()
	and adjust all callers. Avoids some excess strduping too I guess.
	Closes bug #352252.
