Allow id only references (no DBRef)

[GoogleCodeExporter]

At the moment, when you store a @Reference-d field in Mongo through Morphia, it 
looks like:

[
  {"$ns":"Posts","$id":"204967500021_10150745068780022"},
  {"$ns":"Posts","$id":"204967500021_10150745059460022"}
]

However, if the value parameter is given to the @Reference annotation, is the 
ns field really necessary? For large lists, I think it would save a lot of 
space if the above could just be turned into
[
  "204967500021_10150745068780022",
  "204967500021_10150745059460022"
]

Yes, this would prevent schema changes from being backwards compatible in the 
future, but in my case I'm not worried by that. Would you accept a patch that 
adds an 'OmitNamespace' attribute to the @Reference annotation which did this 
collapsing? There's quite a bit of overhead involved in storing sub-documents 
in every single reference.

Thanks!

Thanks for adding this to the Icebox :) Does that imply that if I were to 
submit a patch, it has a chance of being accepted?

Yes (but iceboxing it was a mistake). 

The patch should include an annotation to control this since it could apply to 
@Reference or Key<T> fields.

I think this is a duplicate of #210
