Hello, 

today the PushApplicationID ([1]) and VariantID (iOS example: [2]) are generated w/in the RESTful endpoint class. I'd like to move that into the actual entity - similar to what we today already do with the (master)secret (e.g. [3] or [4]).

Thoughts?

While on it - I'd like to do similar to the PK all ALL entities... Today we have an (odd) Hibernate dependency (see [5]), simple b/c of JPA being lame and not providing "propper" UUID support....  So idea is to

* remove the odd annotation

* do the ID generation "by hand" (like we do on the secret (see above...))

Thoughts?
