make applet a QGraphicsItem not a Group; as bibr explained to me on irc this evening a group is really, really a group ;) iow, the children lose all sense of identity. this causes all sorts of problems for building the sort of interfaces we are aiming for.

however, making them items makes it possible to drag children outside of their parents (c.f. the button applet) which causes another set of problems. i'll look into this tomorrow though. it's 01:00 and i was trying not to work on kde tonight.
