	* app/config/gimpconfig-params.[ch]: added "gboolean allow_percent"
	to gimp_param_spec_unit() and to the GIMP_CONFIG_INSTALL_PROP_UNIT()
	macro. Changed value validation accordingly.

	* app/config/gimpconfig-types.c (string_to_unit): parse "percent"
	correctly.

	* app/widgets/gimppropwidgets.c (gimp_prop_unit_menu_new): show
	the "Percent" menu entry if the param_spec allows percent.

	* app/config/gimpcoreconfig.c
	* app/core/gimpgrid.c
	* app/core/gimptemplate.c
	* app/text/gimptext.c: pass FALSE to disallow percent.

	* app/paint/gimppaintoptions.c
	* app/tools/gimpselectionoptions.c: pass TRUE. Brings back the
	percent feature for fade_length, gradient_length and fixed_size
	rect/ellipse select.

	* app/tools/gimpbucketfilloptions.c
	* app/tools/gimpmagnifyoptions.c
	* app/tools/gimpselectionoptions.c
	* app/tools/gimptransformoptions.c: don't call the the reset()
	functions from the GUI constructors (and reset the options just
	deserialized from disk). Instead, added set_defaults() functions
	which do everything the old reset() functions did (except
	upchaining) and call set_defaults() from reset() and from the GUI
	constructors.
