Add Wii port

[mardy]

Thanks Wouter for this nice game, it's written very well and it was a pleasure to port it :-)

Please note that in order for the port to be complete, we need a 128x48 icon file (png) and an XML manifest. If you can provide them to me (at least the icon and the description text for the manifest), then I can add them to this PR.

We should submit the game to the Open Shop Channel, then.
