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.). committer: Diggory Hardy <diggory.hardy@gmail.com>
