Archer AI - fix [COMMITED]

This fixes Archer type monsters AI.
They'll try to increase range between themselves and the attacker now.


For reference please check this thread --> HERE




Thanks xlinkinx for the contribution and mentioning the missing archer AI behaviour.

I removed the weapon check and added a AI type check, for "lighter" code.

Now only needs approval by DnR.
