tterrag is a meany face and yelled at me for using class.getSimpleName(). So here's an API-friendly re-work of the registration system. This allows all our Items/Blocks to be obtained via the API. Just add a new enum.
I think it's safe to say that if the player is null here, the places we use this check should probably not continue. Will see how it goes.
Also added the check to imperfect rituals and removed a redundant check from the dagger.
