	* app/widgets/gimpdialogfactory.[ch]: added "name", "blurb",
	"stock_id" and "help_id" to struct GimpDialogFactoryEntry and to
	gimp_dialog_factory_dialog_register(). Added typedef
	GimpDialogConstructor which takes a GimpDialogFactoryEntry in
	addition to the parameters GimpDialogNewFunc takes. Added a
	constructor function pointer to GimpDialogFactory which defaults
	to a function that just returns entry->new_func(). Use that
	constructor instead of entry->new_func() for creating
	dialogs. Added public API gimp_dialog_factory_set_constructor().

	* app/dialogs/dialogs.c: register name, blurb, stock_id and
	help_id for all dockables so all the dialog info lives in one huge
	ugly table now. For the global_toolbox_factory and the
	global_dock_factory, set a constructor which creates a dockable
	around the widget returned by entry->new_func().

	* app/dialogs/dialogs-constructors.[ch]: don't create the dockable
	in each dialog constructor. Removes tons of code and reduces most
	constructors to a "return gimp_foo_new(...)" one-liner. Got rid of
	all static variables, they were from a time when GimpDialogFactory
	was unable to manage singletons.

	* app/widgets/gimpbrusheditor.[ch]
	* app/widgets/gimpgradienteditor.[ch]
	* app/widgets/gimppaletteeditor.[ch]: return GtkWidget, not
	GimpDataEditor from gimp_foo_editor_new().

	* app/widgets/gimpdataeditor.c: minor cleanups.
