More cleaning up errors and code. There were a lot of things that needed simplifying. Rather than fix the 3 or 5 copies of the same function throughout the code, I made an effort to use the same function and delete its copies. Created the BaseItemDoor class to hold all the basic door item methods that don't vary between types. That helped cut down on fixing things. Also renamed the door item classes to match their in-game names. There is still a ton of duplicate code out there.
