Also, removed runtime_mapdata_header_t from Surface, as it seems that it is not a proper MapElement type but rather some kind of a sub-element. Anyway, the header wasn't apparently being used for anything (?).
Todo: Scour the code for illegal/forced/unnecessary casts and switch to de::MapElement* instead of void*.
Refactor: Added C++ HEdge class
