exciton-lattice

field: perfect diamagnetism is a bit larger
  can now grab power ups from far away

mod: exciton-lattice - reduce harm by 80%, but after taking collision damage eject a random mod
  eject extra mods if you have recursive stacks

power ups have a bit more air friction
power ups must be in line of sight to be pulled by the player
why mode now gets 100% chance for a second boss power up (up from 50%)
  this should let why mode reach more interesting build depth
laser and pulse got a damage and energy use buff
immune to harm for a second after exiting the power up selection menu
