fixed pet combat ai

[bozimmerman]

There are only 2 pets in the game with ranged attacks, and neither of them were able to use them from a distance. This fixes that issue by:

1. Not having the pet ALWAYS charge at the target when combat starts
2. When the AI decides on an action, choose the range that is appropriate to that action.

(P.S. There is still a minor annoyance to this implementation, btw: -- When the pets ranged attack is on cooldown, they are likely to choose melee and charge at that time. It's not 100% though, and is only mildly annoying, but I may look closer at this in the future).
