	Long overdue core container cleanup:

	* app/core/gimplist.[ch]: added "unique-names" and "sort-func"
	properties and merged the resp. code from GimpDataList into
	GimpList. Removed "policy" parameters from gimp_list_new() and
	added "unique_names". Added new constructor gimp_list_new_weak().
	Made public function gimp_list_uniquefy_name() private.

	* app/core/Makefile.am
	* app/core/core-types.h
	* app/core/gimpdatalist.[ch]: removed. Its functionality is
	entirely in GimpList now.

	* app/core/gimpdata.[ch]: added gimp_data_name_compare() which
	used to live in GimpDataList.

	* app/core/gimp.c
	* app/core/gimpdatafactory.c
	* app/core/gimpimage.c
	* app/core/gimptoolinfo.c
	* app/core/gimpundostack.c
	* app/paint/gimp-paint.c
	* app/tools/gimp-tools.c
	* app/widgets/gimpdevices.c
	* app/widgets/gimptemplateeditor.c
	* app/widgets/gimpundoeditor.c: changed list creation accordingly.

	Made gimp->templates, gimp->named_buffers, tool_info->presets and
	the image's lists of layers, channels and vectors automatically
	ensure unique names.

	* app/widgets/gimptemplateview.c
	* app/actions/file-commands.c
	* app/actions/templates-commands.c
	* app/actions/tool-options-commands.c: removed calls to
	gimp_list_uniquefy_name().

	* app/core/gimpitem.c: removed major insanity where the items
	themselves where ensuring their unique names. Bah!

	* app/core/gimplayer.c (gimp_layer_name_changed): chain up
	conditionally.

	* app/core/gimplayermask.c (gimp_layer_mask_name_changed): removed
	because there is no need any more to keep the parent
	implementation from being invoked.
