level ban setting

new setting: level ban list
bug fix: removed a command to preventDefault on space key, this might break something else
new boss added to level - Temple

snake tails have a lower mass and whip around a bit
auto targeting no longer works for stealth mobs
  snipers, sneakers, ghosters
snipers fire more often at high difficulty, but bullets move slower at all difficulties
hoppers have move gravity, so it feels like they are hopping a bit faster
