New Chaplain abilities: Sigils and Incantations

[Keelin]

Currently it looks like we'll probably end up with a hybrid system that allows for fixed "spells" and the (currently implemented) system of essentially building your own spells.
It'll probably be like "Does this match a fixed ritual?" "No? okay lets do a freeform spell then"
It's bit hard to explain but i hope i can get people something to play around with soon
