Make JAXB Objects Immutable and Add Builder Utility

- Use Immutable-XJC from https://github.com/sabomichal/immutable-xjc
- Update existing JAXB-object manipulations to use the Builder
- Remove jaxbMarshallerTest (as it relies on mutable JAXB interfaces)

Reason for making JAXB objects immutable: I put JAXB objects in the
repository. Depending on the configuration, the repository can be a
simple hashmap; in that case I might end up sharing JAXB objects
between threads. Immutable shared object should make life a little
simpler.
