Make Mongo accessor API pluggable

Bug Description

The Mongo module currently uses Morphia as underlying Mongo access API. Would be cool if this was hidden behind a tiny abstraction so that one can use alternative Mongo Java APIs.

A basic separation of Morphia and Mongodb parts has now been done. com.mysema.query.mongodb contains the general part and com.mysema.query.mongodb.morphia the Morphia specific part.

For an alternative ORM layer on top of Querydsl Mongodb you would need to

* subclass MongodbQuery like MorphiaQuery to supply transformer etc
* subclass MongodbSerializer like MongodbSerializer for annotation based field name extraction
* create an annotation processor like MorphiaAnnotationProcessor

Study the Morphia layer to see how it's done. To use the dependency without Morphia just add an exclusion. Using code from the com.mysema.query.mongodb package is without Morphia references.

Thanks for the quick fix. I#ll give it a try next week. Is there a way to grad a nightly snapshot or the like? I couldn't really find a current one in the Maven repo.
