Fleeing MOBs

[mollymillions]

If your feeling adventurous, here's a hack to enable fleeing MOBs that uses the existing Fear spell code. The Z axis pathing isn't that great (probably very bad for dungeons).
Line numbers are approximate!

Isues:
-Some MOBs on the current DB have no regen therefore their HP will never recover and they will never stop fleeing.
-A high level MOB will flee from a low level PC.
-Assisted MOBs will flee.
-MOBs flee at full speed regardless of HP.
-Some MOBs should never flee.
-Z axis pathing is incorrect.
