Fix Librarian Story Quest (#2218)

* Fix Librarian Story Quest

* People die if they are killed

You want to die people instead of remove them so they play their sweet death animations.

* Nope. I take it back. Scriptlib is the wierd one to think removeEntity removes the entity.

* One must stop editing the code directly.

* Update EntityType.java

* Add warnings per Hartie

* Per Hartie, change getEntityType to EntityType
