How to add a new class:

1) Create a new class file and name it <classname>.class, replacing <classname>
	with the name of the class.  Follow the format outlined in the
	class.class file.  NOTE: In the skill part of this file, you only need
	to add the skills that this class will get, all skills not included in
	this part are automatically set to level LEVEL_IMMORTAL
	and difficulty of 0 for that class.

2) In the load_class function (db.c), add a new case statement near the top of the
	function.  Just copy the last case # statement, increase the # by 1, and
	replace the class's name with your new class name.

3) In merc.h, increase MAX_CLASS by 1.

4) Recompile and run the MUD!
