Unwrap Event Exceptions
This was a useless exception wrapper that ends up making
stack traces harder to read as well as the JVM cutting off
the important parts

Nothing catches this exception, so its safe to just get rid
of it and let the REAL exception bubble down

Subject: [PATCH] Provide Chunk Coordinates as a Long API
Allows you to easily access the chunks X/z as a long, and a method
to look up by the long key too.
