DATADOC-115 - Upgraded to Querydsl 2.2.0-beta4.

Enabled treatment of not annotated classes as embedded documents to let Querydsl create query classes for them. Annotated BasePerson with @QuerySupertype as Querydsl seems to need this annotation to create the query class for super types in the 2.2 branch.

That issue is tracked in https://bugs.launchpad.net/querydsl/+bug/776219 so that we should be able to remove the annotation as soon as this one is fixed.
