Crazy Thruster Business

-MAXIMUM EVASION OPPORTUNITIES
-Even though I added a gorillian things to Player.as, I think in general
it handles drag and accel a little better (can prob. be refactored
further actually)
-Added SIZE to Exhaust particles so that big ass ships can have big ass
particles
-Got rid of getFirstAvailable() in Particle Manager, replaced with
recycle() as per Mark's greatest advice
