Prevent players from farming monster king aggro by setting 30 seconds ticks.

You can only generate up to 5 aggro every 30 seconds, non-cummulative.

If you kill a level 30 monster and then a level 60 monster, 2 aggro is generated.
If you kill two level 30 monsters, 1 aggro is generated.
If you kill a level 90 monster and then a level 60 monster, 3 aggro is generated.
If you kill a level 150 monster, wait 45 seconds, and kill a lv 30 one, 6 aggro is generated.
