Add docking capabilites to the toolbox so it would be possible to dock another dialog to the top, bottom, left or right of the toolbox or dock the toolbox on the top, bottom, left, or right of another dialog window. (In multi-window mode and single-window mode)

From an irc discussion:
(08:44:36 AM) jbaker: speaking of ui, is it possible to move the toolbox to the right of the image in sw mode ?
(08:48:33 AM) guiguru: jbaker: should be
(08:48:55 AM) guiguru: it is free tear off and docking in swm
(08:50:14 AM) jbaker: guiguru: i think the toolbox is a different widget than the other dialogs, as far as I can tell there is really no place to grab it...
(08:50:43 AM) guiguru: it is different, but that needs to be fixed then
(08:51:23 AM) Death: Grabbing wilber would make sense for me...
