[ALL] Overhaul to internal system

This massive change replaces the old "Rom" struct system with a new one that have different objects for each major item type. This required a lot of work and a lot of changes and has unfortunately been untested. But this is the first step in moving away from using structs. The next major step is converting Dat over to this as well.
