Fast Update!

I did some code cleaning and bugfixing:
I wasn't happy to know all of those bugs were fixed, and out here there were not.
So here is another update in a so short time!

most of the changes are not directlyvisible: performances and stability are this update's keywords.

Here's a short changelog: - Fixed more than 140 potential bugs - Fixed altimeter bug - Added high-speed dive damage - Fixed radius damage - Fixed some audio issues - optimized code performances
