	Fixed GimpData's default "writable" and "deletable" behaviour:

	* app/core/gimpdata.c (gimp_data_init): default to writable and
	deletable == TRUE (something that has no filename was never loaded
	from disk and can't be undeletable or read-only).
	Fixes bug #134274.

	* app/core/gimpdata.[ch]: added new function
	gimp_data_make_internal() which frees the filename and sets the
	data's flags accordingly.

	* app/core/gimp-gradients.c (gimp_gradients_add_gradient)
	* app/core/gimpbrush.c (gimp_brush_get_standard)
	* app/core/gimpgradient.c (gimp_gradient_get_standard)
	* app/core/gimppalette.c (gimp_palette_get_standard)
	* app/core/gimppattern.c (gimp_pattern_get_standard): use the
	new function for internal data objects.

	* app/core/gimpdata.c (gimp_data_save, gimp_data_delete_from_disk)
	* app/core/gimpdatafactory.c (gimp_data_factory_save_single):
	bail out with g_return_if_fail() is the data is not writable
	or deletable.

	* app/widgets/gimpdataeditor.c
	* app/widgets/gimpdatafactoryview.c: changed accordingly.
