bounceBoss balance and bug fixes

difficulty balance per level
  mob harm done is reduced about 2%
  player damage is increased about 2%

slasher mobs do 20% less damage
  this is because they killed me on my last run and I'm bitter
mantisBoss is invincible for a less time
Zeno's paradox removes 1/10 -> 1/12 health every 5 seconds

slow, stun, plasma, foam, neutron bomb effects now only slow mobs down to a minimum speed of about 2-4

bug fixes
  bounceBoss deals with slow effects in a less buggy way
  final boss didn't kill invincible mobs when it dies
