add professions (aka. character classes)

[scionaltera]

It's just kind of a copy of species for now but it's a start. It's just a tag that gives you two additional pre-set stat or effort points. I wonder if it would be worth trying to de-duplicate all that code and make it into just a generic tag or template or something...?

I'm calling it professions because "class" is a reserved word in Java and it's a ton easier to just use a different word instead of having something like mudClass everywhere. I also find it a bit more true to what it actually is. Someone can choose to be a fighter or a bard or whatever to make a living, and maybe change to a different job later (multi-classing), and I've never seen it as something you're stuck with forever as "class" implies.
