A new header named TypeList.h and the type lists have been redefined in this new file. All the types have been renamed from `TypeListTag*` to `TypeList*`. TypeListTag.h has been gutted to provide deprecated versions of the old type list names. There were also some other type lists that were changed from using the old `ListTagBase` to the new `List`.
