[pnpgm] join fight

[Alex Koponen]

Z'leyra, seeing no enemies amongst the humans and thinking that they can 
be dealt with later runs to join the fight. Hopefully this will reduce 
the damage the party and humans will receive by putting down the Vong 
before the can do damage....and she will be closer to those that may 
need her healing.

If there are open lines of sight for using her sling she will use it to 
send send magical bullets against the Vong, otherwise she will loop it 
around her wrist while readying her warstaff and join the melee.
