Arena Combat

I have added the rules for Arena Combat. We plan to have this option available for the November session. In support of those rules I have changed the rules for the Gladiator Feat to the following:

Gladiator (Feat, Combat 3, Perform) You get 2 experience points the first time you participate in Arena Combat and 1 more point for the next 2 times (for a maximum bonus of 4 exp).
