	* app/widgets/gimpchannellistview.c: enabled setting component
	activity. Connect an "extended_clicked" callback to the "To
	Selection" button for add/sub/intersect.

	* app/widgets/gimpcomponentlistitem.c: removed some commented out
	code.

	* app/widgets/gimpdrawablelistview.c: stuff.

	* app/widgets/gimplayerlistview.c: set "Raise" to insensitive if
	the active layer has no alpha.

	* libgimpwidgets/gimpbutton.c: fiddle around correctly with
	GtkButton's internals.
