[CLOSED PR] Reworks wraith, adds specialization paths; Harbinger, Plaguebringer, T...

[Frank_Stein]

IMO, just have all candles work as wraith detectors, with the flame turning blue when they're a certain amount of tiles away, intensifying as they get closer, and finally revealing them if they're right by it.

Then just make all candles finite resources, with more being able to be made. (Beeswax? Honey and crayons?)
