Thanks BAIL for the tip about auto module loading

You may want to look at the other module include files, they have special tokens at the top which lets them autoload.

You might want to describe a little bit about how this works if you want people to utilize it.

Also, you should consider making it work with strings and floats, AMXX has easy functions you can use for modules to convert the pawn floats/strings to c++.

Anyways great job! We don't get very many modules compared to plugins.
