Fixes to get the Bot working.

I forked your code and tried to run the bot but it complained about passing arguments to commands/listeners that didn't have constructors, so I have made a fix for it which attempts to use arguments and if that fails then it tries to construct without arguments.
If the config. file has arguments but the command/listener doesn't accept them then it will warn the user that the command doesn't accept the supplied arguments.

I also fixed the keywors mistake to keywords because it failed to start due to it being misspelt.
I then noticed that FutileFreedom also fixed the second bug but you haven't committed his pull request yet (I cloned yours and it still had the error), found here: https://github.com/pogosheep/IRC-Bot/pull/25

Thanks. =)
