Prevent lower level mobs from attacking the higher level players

[ShadWing]

Level 1 to 25 monsters do not attack level 36 players. That is how it was in original game.

As discussed on Discord before this was submitted, the aggro range should grow or shrink according to the level difference, not abruptly disappear after a given threshold.

You could try implementing it that way if you want? If not, someone else will get around to it eventually.

Seems to be superseded by 540c37a5, going to go ahead and close this.
