	* app/core/gimptooloptions.[ch]: added API to delete saved
	tool-options.

	* app/tools/gimp-tools.c: don't deal with saving presets, just
	load them on startup. Create the tool-options directory when
	saving tool-options.

	* app/core/gimptoolpresets.[ch]: added new signal that is
emitted
	whenever the presets changes. Create the tool-options directory
	when saving a preset.

	* app/widgets/gimptooloptionseditor.[ch]: listen to the
"changed"
	signal of GimpToolPresets and queue an idle save.
