Refactor everything to use a base ILump interface, and a Lump class implementing it to use in place of regular List. Refactor lump structures to use an ILumpObject interface. Eventually Lump<T> will enforce T is ILumpObject, there are some other things to do first. Use Path class to simplify some code in BSP.
