	* app/gimpcontainer.[ch]
	* app/gimpcontainergridview.c
	* app/gimpcontainerlistview.c
	* app/gimpcontainerview.[ch]
	* app/gimplist.c
	* app/gimpmarshal.[ch]: the GimpContainer has a new virtual "reorder"
	method which is much more eficient then the current remove/add
	braindeadness when renaming data objects.
	Changed the views to connect to "reorder" and call the
	GimpContainerView's new "reorder_item" method which then does
	the right thing in the view subclasses.

	* app/gimpdatafactory.c
	* app/gimpdatafactoryview.c
	* app/gimpdatalist.[ch]: removed the data list loading and saving
	stuff from GimpDataList because that's the job of the
	GimpDataFactory.

	* app/brush_edit.[ch]
	* app/brush_select.c: cleanup.

	* app/gradient_editor.[ch]: changed it to work like the brush
	editor: return a GradientEditor pointer in the constructor
	and statically store this pointer in the gradient selection file.
	Removed the global "g_editor" variable and added tons of
	GradientEditor* variables to function calls so they know their
	context without the global variable.

	* app/gradient_select.c: changed accordingly.
