Bug Fix: Stop Pets Fleeing

[Angelox]

Thanks a ton for your fixes Derision- I have this one and your other 'Pet HP Bar out-of-combat update' fix together with a few others posted at my web page.
I posted windows executables and source for who ever wants to try it out. They all are tested and work fine for me.
Also added is the 'closest_zp = NULL;' in Leikas MQ-Cheat detector code, so you either would have to use my database ( has update to zone points already) or up date your zone_points as explained in the MQ-Cheat detector thread
The 'Pet HP Bar out-of-combat update' fix was a nice one too, always bothered me ever since I started EqEmu
