(WIP) Start implementing ICombatant
Start by replacing `hitMob` with `takeDamage` interface function. Simplify `pcAttackChars` a little by utilizing the new interface, then add more interface functions as needed. A lot of the combat logic is tied to the `Mob` class. Need to start moving stuff over to CombatNPC.
