	* app/commands.[ch]
	* app/menus.c: first version of the new layers and channels dialogs.

	* app/gimpcontainergridview.c
	* app/gimpcontainerlistview.c: allow creation with a NULL container.

	* app/gimpdnd.[ch]: added generic DND functions for all drawable
	types (not just setting the DND icon). Started to remove code
	duplication.

	* app/gimpdrawablepreview.c: with some magic calculations and ugly
	assumptions the drawable previews now look exactly like in the old
	L&C dialog.

	* app/gimpimagepreview.c: no need to say "return" at the end of a
	void function.

	* app/gimppreview.[ch]: added the "is_popup" boolean also to the
	default constructor. Call gimp_preview_set_viewable() before
	calculating the preview size.
