Threat display

[Tremolo4]

Threat display functionality was removed some time ago, presumably because UnitThreatSituation etc. are not present in 2.4.3.

I have implemented UnitThreatSituation using LibBanzai-2.0 and ThreatLib-2.0. Works surprisingly good!

The uOF threat element uses UNIT_THREAT_SITUATION_UPDATE, UNIT_THREAT_LIST_UPDATE which are also not present in 2.4.3. I replaced those with callbacks also from LibBanzai and ThreatLib. Works fine as well. ThreatLib callbacks are rate-limited (2 per second).

WIP, because I have not tested this in a raid yet. There are some debug prints still. Will report here again.

This is the second change that we were write in at the same time and our realisation have difference. To make sure it won't happen again, let's establish communication.
Join our discord server where we can discuss that.

Done.
Looking forward to your solution (maybe mine is of some help still) :)

Rebased.

Added some Fixes - my PLAYER_ENTERED_WORLD callback was crap before (whoops).
Now includes full implementation of UnitThreatSituation (not needed for threat element).
According to my testing, there are no performance problems (regarding ThreatLib).

Removing WIP tag, because I think it works very nicely. Still need to test it in a full raid though.
