[Discontinued] Utility Staffs Classic

This really shouldn't have taken as long as it did, but I had no way to progress on the mod for a little over a week, sorry if the key problem affected you.

Changes:

Added functionality for the mysterious keys to drop from the Plasma Guardian (I'm sorry that this was not in the earlier versions this was a big mistake on my part).

Changed plasma staff model to a more unique version.

Added limit to enderglass staff so that it cannot be used below y level 50 in the overworld (so it's not an extremely easy way to return to the surface).

Added limit to enderglass staff so that it cannot be used above y level 100 in the nether (so you cannot get through the nether roof).

Changed plasma chest collision size to match its model.
