Add IrrlichtDevice::setWindowSize (implemented only on X11, will try Windows next).

A few minor changes to the GUIEditor:
- Displays the window-size
- Update (rarely) when Window now active
- Sleep after drawing to prevent update-delays on resizing
- Driver choice now only for available drivers
- Kick out the "Tools" tab as it's unused so far and just irritating users.
