What does this pull request do?

Moves the Jailer of Faith QM exactly every 30 minutes from when it lasts appears. The original implementation is completely broken, as mentioned in #3632. There is some slight contention on whether it moves every 30 minutes or 15 minutes, but as best as I can tell it was either updated in a patch to 30 minutes, or people are confusing the generic 15m (at the time) respawn on QMs vs the 30m move timer.

The code mimics Phantom Worm's movement code but requires some extra logic to track the case where JoF may pop and die before the timer triggers, requiring the timer to be reset (which is not particularly easy and instead I opted to just start a second timer and ignore the initial timer when it triggers). Phantom Worm conveniently ignores this problem because the move timer is so short it's not really noticeable.

I did not update Ix'Drk but if this PR goes through I can give it similar treatment.

Steps to test these changes

5 locations for pop:
-- North / Hume tower !pos -420 0 -157 35
-- NE / Elvaan tower !pos -157 0 -340 35
-- SE / Galka tower !pos -260 0 -643 35
-- SW / Tarutaru tower !pos -580 0 -644 35
-- NW / Mithra tower !pos -683 0 -340 35

1. Find ??? and wait for it to hide
2. Wait 60s then find ??? in new location
3. Wait for it to hide again exactly 30m after it re-appeared (test default move logic)
4. Spawn Jailer of Faith and kill before the 30m timer triggers (test timer overlap code)
5. Make sure the QM moves exactly 30m from when the QM reappears after killing him
6. Spawn Jailer of Faith, and hold it for 30 minutes, then kill it (test timer cancel code)
7. Make sure the QM moves exactly 30m from when the QM reappears after killing him
   It's much easier to test by changing the timer to 30 seconds!

LGTM 🚀

Is it known what happens during server restart on retail? Whether or not the previously chosen point persists, or if its rerolled?

Unknown afaik, however we don't currently persist any of the randomization in Sea. Faith, Temperance, Ix'Drg, Ix'Drk, and Fortitude are all randomized on zone initialization

Sorry, still learning but just found out there's a clearTimerQueue function which I can use instead of tracking the number of timers running, so I'd like to switch to that and simplify the code a bit before submitting.
