Remove a class/Add a class

[Wolf Kanno]

I'd remove the thief class and replace it with the FFIII version that actually does something useful, though I would keep the FFI Ninja as it's upgrade.

It occurs to me that a Thief from FFIII would completely negate the need to do the first sections of the game. :o

Don't consider that a problem since I feel the game doesn't really pick up until you start actually taking on the fiends. smurf the elves.
