Fix Namespace Prefixes in Marshaled Messages (msg: instead of ns#:)

- Implement own NamespacePrefixMapper that maps prefixes depending on
  whether a msg or a mzs object is being marshaled.
- Namespaces are not hardcoded but extracted from jaxb's generated
  sources (somewhat indirect, can be considered a hack, but there's no
  public API to extract namespaces)
