Adds a scrying orb for wizards

Item taken from /tg/.

This item, first, grants wizard x-ray sight upon buying it. Second, when used, it allows the wizard to ghost, but being able to return to the body, similar to cult's astral journey, minus the damage. It's usable be anyone, not just the wizard, but x-ray vision stays with the person who bought it.

If you believe that this should pass through the forum before being merged, I'll close it.
