	* app/patterns_cmds.c
	* tools/pdbgen/pdb/patterns.pdb: removed the GimpBrushP and
	GPatternP types and use ordinary pointers instead.

	The following stuff makes the "no_data" behaviour consistent. As a
	side-effect it should make the gimp work when there are _really_ no
	brushes/patterns/gradients.

	* app/brush_select.c
	* app/pattern_select.c: set the initial brush/pattern name to "No
	Brushes/Patterns available" instead of "Active".

	* app/devices.c: set the device contexts' brush/pattern/gradient
	names if we started with no_data, so we find them on refresh.

	* app/gimpbrushlist.c: set the name of the standard_brush to
	"Standard".

	* app/gimpcontext.c: don't replace the current
	brush/pattern/gradient's name if the new one to be set is the
	standard one. Together with the change in devices.c, this ensures
	that we get what is set in devicerc. Minor fixes.

	* app/gradient.c: changed gradients_init() to work like the other
	data init functions. Only insert a default gradient in the
	gradients list when the editor is opened (this means that the
	gradients now behave like brushes/patterns when we start with
	"no_data").
	New function gradient_update() avoids tons of useless redraws of
	all clist gradient previews whenever the gradient editor wants to
	update it's large preview.

	* app/gradient_select.c: don't segfault when the user tries to
	drag from an empty gradient list.

	* app/patterns.c: set the index of the standard_pattern to -1 to
	indicate that it's not part of the pattern list.
