Add imbuement altar

- Adds imbuement altar block and associated tile entity
- Adds basic functionality for imbuing wizard armour (other stuff to be decided)
- Incorporates imbuement altar into glowing overlay model event (this could do with being tidied up and generalised)
- Adds a TESR for the ray effect (based on some of the oldest code in the entire mod, which definitely needs improving!)
- Adds a simple sound effect for the imbuement process, needs upgrading to a ticked sound later
