laserLayer

mob: laserLayer - leaves behind lasers that persist for a few seconds
ghoster mobs do 66% less damage, but they eject your ammo

grappling hook tech rupture renamed swarf
  fires several nails at nearby mobs, not explosions
grappling hook 6->9 energy per second
CIWS 18->10 energy
reel +40->75 energy reeling blocks
wormhole 5->7% duplication
cloaking no longer drains energy, this fixes a can't cloak bug
  dazzler no longer drains energy
    dazzler range reduced by 15%
    dazzler stuns for 3->2 seconds
zero point energy 100->166 max energy
expansion 40->77 max energy
annihilation -33% of max energy -> 10 energy
dynamical systems is no longer a field tech  35->30 damage
tessellation is no longer a field tech  50->35 defense
yield stress removed
  topological defect 80->111% damage
  brittle 80->111% damage
commodities exchange  6-12 -> 10-14 power ups
heat engine 50->40% damage
flame test grenades clusters explode 40% faster
alternator uses 10->0% energy for harpoon

finally made a shared vertexCollision function
  this might cause some bugs with laser-like effects...
