Update V1.2

Yea. V1.2, which you have probably been waiting for for half a year, is finally being released.

This Updates has many changes in the engine:

• added -d as a flag to main.pyw to activate the developer/debug mode
• we have switched from pygame to pygame-ce
• removed the windows/linux init code and change it to a pygame-ce command
• rebuild the Homescreen to make it look better (the most changes are only interesting for developers) (and the game has now on the game page a background)
