Move the QGL resize hacks from extender to extenderapplet. The only applet atm for which this hack is necesarry is actually extenderapplet, in the future we will have better layouts, and it won't be necesarry at all, and for now it avoids breaking panel layouts when removing the last extenderitem from an extenderapplet.
