	* app/core/Makefile.am
	* app/core/core-types.h
	* app/core/gimpimagemapconfig.[ch]: new GimpViewable subclass
	which has a "time" property. Sets the object's name to a date
	string if a time != 0 gets set. Has a compare function which first
	sorts the objects with a timestamp in MRU order and then the
	objects without timestamp by name.
