AvoidIt 1.0.0

This is @reapler's AvoidIt plugin for vanilla.
I noticed there were some errors thrown, related to the code it uses, as I was plaiyng around with similar pathfinding code myself.
For some reason, I could also change the settings on 1 character out of many.

So I decompiled his plugin and compiled it again with minor changes.

For anyone who cares - apparently:

PathFinder.Pather.ReportBigDangerArea(woWUnit.Position, radius);

throws a NullReferenceException (even though Pather, wowUnit and radius are all not null) - this doesn't happen on EVERY character.
 

PathFinder.ReportBigDangerArea(woWUnit.Position, radius);

works fine, so that's basically the extent of my changes.
