Try to generate builder setter for JAXB generated collection accessors

[maybeec]

Due to the fact, that JAXB does not generate setter and getter for collection, but only a getter, which leaks the reference to the collection, we should discuss whether it is possible to support generation of builder pattern setter also for this type of properties...

Needs discussion, whether we can handle this is a sufficient generic way.
