geometryChanged is a signal in QGraphicsWidget in Qt 4.7, conflicting with Applet's. but they do the same thing (seems others ran into the same issues we did? :) .. so provide a binary compat preserving way to move Applet's signal "out of the way". right now we are getting warning msgs on console due to it, doulbe signal emissions and that all just smacks of bugs waiting to happen.

thanks to Gof for the protected method idea, and Alexis for his fast response to reported issues with the signal as implemented in the pre-release versions of Qt 4.7
