Troll? Anyone? Too bad! *puts on Enderman*

Yeah... that's kind of a hint for what changes I did. No dev release
this time. Though - you can feel free to compile the code and test
around.

Move the dependcheck, commandhelplist, and vanishplayers files into one
main area (aka the PluginUtils file).

Troll upgrade! Now, when you do /antipmc troll, it has a chance of each
type. Slime, Pigderp, and Slenderman (really an Enderman just renamed).
Also, fireworks!

Chat Listener changes. New FORMAT string, in order to help make the
changes and such. Also actually tells the console what was going to be
logged (or was logged) when an IOException occurs.

Enabling - Add SecurityException to the catch list for creating the
log.yml file. Also rename the checkers to "Listeners" in the dev mode
startup.
