Projectile now has lifeSpan - it disappears after some time (default 5seconds)
Weapon now has projectileSpawnLocation - some location defined by (probably) empty GameObject (usually child of Weapon object)
added simple scene (with simple mech and simple dummyBots)
Merge branch 'DenatMadTestLab'
added control for xpad 360
added part of pawn script which makes a collider part of some pawn (it will pass the collision data to the pawn)
