Absolutely Barbaric Beta 0.5.2c: game controller support!

I've done some maintenance to the game and the code and added not only fill game controller support for all versions but also fixed some bugs that have annoyed me for quite some time now 😉

Here's the full change log:

- Full game controller support added to all versions

- fixed the game over sound starting twice 

- added a dead player body to the death animation

- the game over screen will come up now actually after the death animation has finished
