Title: DATAJPA-523 - Make Specification implement Serializable.

DATAJPA-523 - Make Specification implement Serializable.

Specifications now implements Serializable to be able to transfer them across systems boundaries. Introduced special Serializable Specification types for composed and negated Specifications.

Note that currently only Hibernate and EclipseLink expression structures implement Serializable - OpenJPA's don't.
