2003-02-08  Michael Natterer  <mitch@gimp.org>

	* app/config/gimpconfig-serialize.c (gimp_config_serialize_property):
	the virtual serialize_property() returning FALSE doesn't mean the
	serialization failed but that the function didn't handle the
	property, so don't error but continue with the default
	implementation. Print newlines after properties only if
	indent_level == 0.

	* app/gui/tool-options-dialog.c: added tool options saving/loading
	as quickly hacked proof-of-concept.

	* app/paint/paint-enums.[ch]: added enum GimpInkBlobType.

	* app/tools/gimpinkoptions.[ch]: ported to object properties,
	cleanup.

	* app/tools/gimpinktool.c: changed accordingly.
