Long Standing Bugs

Reading over Nene's movement code for refactoring and gun code (in general) I have found a number of minor bugs.

First, it seems the Heat Wave system is broken in it and never could have worked. Since it never sets the heat waves escape angle. Second, it seems a weight in the gun never worked correctly. Since the timeSinceVelocityChange is always 1 (or 0 on change).

There are probably more, but these are the ones I have found so far.
