	* app/text/Makefile.am
	* app/text/gimptextlayer-xcf.[ch]: new files that load and save
	text layers to/from XCF.

	* app/xcf/xcf-load.c
	* app/xcf/xcf-save.c
	* app/text/gimptextlayer.c: removed that code here and use the new
	functions instead.

	* app/text/gimptext-parasite.[ch] (gimp_text_from_parasite): added
	a GError parameter.

	* app/text/gimptextlayer.[ch]: store the name of the parasite that
	the text layer was created from (if read from XCF). Remove the
	parasite when the text layer is edited. If a text layer wasn't
	touched, the original parasite is written back to the XCF file.

	* app/text/gimptextlayout.c (gimp_text_layout_new): handle a NULL
	text string.

	* app/tools/gimptextoptions.c: implement GimpToolOptions::reset
	and save the text across a reset.
