* remove extenders (never panned out, used by exactly two components that we can find .. anywhere) * move animations to libplasmagqv * schedule js anims to be put into the js scriptengine * move all QGraphicsProxyWidgets, except for IconWidget which is still used by PopupApplet, into libplasmaqgv * create a subclass-able private class for Applet TODO: move out icon widget, address FIXMES in graphicswidgetappletprivate.cpp and decide how to register the "right" private class for instantiation in Applet ctors
