Added chargingLazer and AttackSpeed changes (READ)

Charging lazer still not fully functional, shooting left is glitchy
Attackspeed has now been changed to base 10 seconds (so whatever the
attackspeed is is subtracted from 10000)
Also, if the attackspeed is negative, it means the bullet will handle
that itself (charging lazer is an example...the killSelf() method sets
the holders canshoot to true)
