This will have impact on Chase and Follow Movement.

* Refactor code to check if a new position is required for the MMGen into the new function RequiresNewPosition
* Refactor code to get the current targeted distance into function GetDynamicTargetDistance
* Change ChaseMMGen (angle = 0.0f case) chase to best contact point, not zero angle.

Thanks to Cala and X-Savior for testing. Special thanks to cala for also suggesting improved values for the magic numbers

[s2101] This is used to prevent creatures from pulling too many nearby monsters, for example during certain scripted events.

A good example is Mr. Smite in the Deadmines. There are two guards at the
bottom of his bridge which trigger aggro for him, but if he is missing
this flag he will also pull nearby mobs on the ship, which is not expected
behavior.
