refactored and updated BerkeleyJE
added verification checks prior to serialization to see if objects can be successfully deserialized.
Merge branch 'master' of github.com:thinkaurelius/titan
updated poms to 0.2.2-SNAPSHOT
fixing serialization test
needed to disable testDataTypeValidationOnProperties because MockSerializable has no equals implementation and hence Titan cannot verify de/serialization. Revert when https://github.com/tinkerpop/blueprints/issues/374 is fixed.
If id is a string, do a Long.valueOf (not Double.valueOf)
added DateSerializer and corresponding test
