Currently, blacklists are using an outdated method (EntityList#getEntityString) for matching entities. It works, but it would be more logical to use registry names ("minecraft:sheep" instead of "Sheep", etc.) The entity string matching can be left in place for backwards compatibility.

It would also be nice to have a config option to automatically ban all bosses from becoming blights, so it doesn't need to be done on a case-by-case basis if the user does not want to.
