Makes spookoween things a bit nicer.

* Orders trigger_spooky_trap from most likely to least likely
* Adds and removes spaces where apropriate
* Skeletons no longer return to their lockers but disappear in smoke.
* Decreased the maximum number of bats by one
* Removes some semicolons
* Removes some returns in favor of else-if chains
* Rewords some things to sound less silly

Yeah this is pretty much done. The code should look pretty now.
