Remove dead / unused code regarding conversions
There's a lot of code that was previously used for doing conversions between C++ / Python types (apparently relying on extensive RTTI / typeid manipulations), which got superseded by a cleaner templated approach. The old code was left behind, and there were a few instances where it was still used even though it wasn't needed, like in QtScript typesystem XML and shiboken's enum handling. Remove the old code, apply the small changes needed to make it work with new the code. This is cleanup to reduce the confusion regarding conversion behavior, and also preparation for a proper implementation of handling "void*" types.
