request process. -->

Removes a lot of magic effects the chaplain like purifying cult runes
and healing people by smacking them on the head and immunity to cult
conversion
Makes the only chaplain amour witchhunter because templars are generic
(I know witchhunters are still pretty generic but it fits more with the
srm)
