Work on the Gui: some of the framework for drag & drop. Also made Window an IWidget.
Implemented getWidget(x,y) to find the widget under this location for IWidgets (but not Gui).
Made Window an IWidget and made it work a little more similarly to widgets.
Implemented callbacks on the Gui for mouse events (enabling drag & drop, etc.).
