[Improvement] Flee Overhaul

[fryguy503]

Description

There was a number of issues with the current flee code that caused some heartburn. I merged the TAKP logic with our rule and extended flee checking logic to create this.

• Mobs will properly check Race and Faction of nearby mobs
• Mobs will check flee status on HP change (damage or heal/regen) to determine if they should continue to flee (Issue on current code).
• Mobs will appropriately slowdown/speedup when their HP drops/increases.
• Mob pathing is greatly increased to not push them outside of mesh/player accessible areas.

Adds #fleeinfo for mob flee status and potential

Credits go to https://github.com/eqmacemu/server for a very large portion of this code.

This needs full testing before being merged. 1 other server reported issues with fleeing causing mobs to pop underground, but I am not sure how much that was existing issues with mesh and z axis and how much may have been caused by this PR.

Recent adjustment helps with mobs following furthest Z mesh when multiple Z planes of near Z mesh are on top of each other.

Overall, I don't see a ton wrong with this. I marked a few spots that potentially have minor changes to make but even if we didn't make them it would be fine.
