GW2D v1.3 - Added Android version

Added the .apk file as an option for the download. Since the game is fully playable with the mouse, a port for Android was very easy to make.

I planned to change the UI, at the beginning, since there are a lot of icons and small texts, but I accidentally played it today on a standard smartphone and I was surprised that I've been able to read the texts and play it. Still, better to do it on a tablet.

Cheers
