	* app/widgets/gimpdock.[ch]: added "book_added" and "book_removed"
	signals. Removed the "destroy_if_empty" flag and destroy empty
	docks in book_removed's default implementation.

	* app/widgets/gimptoolbox.c: implement "dock_added" and
	"dock_removed" and set the window to freely resizable vertically
	if it contains dockbooks, and to the current behaviour of snapping
	to multiples of tool_button height otherwise. Fixes bug #93309.

	* app/widgets/gimpimagedock.c: changed accordingly.
