Another engine update

Updated engine with a fix for AMD GPU owners. The game should no longer crash if GPU skeletal animation is not supported in drivers (it will automatically disable GPU skeletal feature with fall back to the old method)

NOTE #1: You might have to restart Steam client to get the update

NOTE #2: I have Steam Cloud working, however, if you play on different OS, you will get sync issues and will loose all of your progress (if you play on WinXP and then want to continue on Windows 7, it won't work). So, waiting on Steam to resolve this situation and once it's resolved (I hope it can be resolved), Steel Storm will be utilizing Steam Cloud.
