Created a 'Being' class (would have been called character, but that
confliced with the native Character class). the Player, NPCS and
monsters will all inherit from this and get stats and health, etc.

Also created stat classes. I'm thinking that way things can be calced
differently for each stat. Might be overkill, but I'm thinking it may
come in handle for specifc methods that a stat may do. Like different
attacks can be handle in the attack stat.
