Rewrite the entire GUI using something != tkinter

[cloudstrife9999]

The VW GUI is currently built on the top of the tkinter library.

This is known to cause incompatibility issues, and graphical bugs with MacOS and Windows (e.g., see issue #4).

It would be better to re-build the GUI using a more modern and more compatible library.

A.K.A. make VacuumWorld fully compatible with MS Windows, and MacOS.

I recon pygame is worth a try for this... its a bit of a shame that VW is getting heavier !
