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

[Bartimeus]

The spirit candle has been modified a little. It now instead reveals every wraith to everyone in a 4 tile radius and has a lingering effect on the wraith of approximately 3 seconds. The candle doesn't work in backpacks. This solves the issue of the candle being abused to see blobs/ghosts/invisible people. You can still use it in hand to snuff it out permanently and force wraiths to materialize for 30 seconds while darkening the are for 10 seconds.

Here it is in action, without the sprite for now.
