gamma ray rename free-electron laser

"gamma-ray laser" renamed "free-electron laser" to make more scientific sense
  since gamma rays would go right through walls
laser diode now makes lasers blue
free-electron laser can no longer work with laser diode

pressure wave has a bit more damage
  crouch mode works different (much higher fire rate, low arc)

integrated armament gives 35% dmg (was 22%)
  but I fixed a bug where it gave an extra 33% ammo

mine gun gets 25% less ammo
all mines do 30% more damage

trying to make shotgun better at close range and worse at distance
  shotgun slug is much slower, but does 60% more damage
  nail shot has a 20% wider spread, and is 20% slower, but does 20% more damage

finalBoss has 15% less health

to balance all the buffs
  ammo power ups give 15% less ammo
  damage done by mobs now scales up a bit faster each level
  damage done by you now scales down a bit faster each level
