changed drag source stuff to allow multiple data types. Changed DND source

	* app/widgets/gimpdnd.[ch]: changed drag source stuff to allow
	multiple data types. Changed DND source API to speak in terms of
	add()/remove() instead of set()/unset(). Added GimpDndDragFileFunc
	typedef and gimp_dnd_file_source_add().

	Unfortunately GTK+'s DND API lacks symmetry here (no GtkTargetList
	based API for drag sources), so we cannot really change drag
	sources on-the-fly and need to set GtkTargetEntry arrays manually.

	* app/widgets/gimpcolormapeditor.c
	* app/widgets/gimpcontainertreeview.c
	* app/widgets/gimpmenuitem.c
	* app/widgets/gimppaletteeditor.c
	* app/widgets/gimppreview.c
	* app/widgets/gimptoolbox-color-area.c: changed accordingly.

	* app/widgets/gimpdocumentview.c: ditto. Additionally offer
	"text/uri-list" so it's possible to drag images from the document
	history to the file manager or browser.
