Omit null valued properties when deserializing POJOs

It's typical to use JSON as a minimal/lightweight serialization format. Usually, for the sake of brevity, a good signal/noise ratio, and sematic correctness, properties which don't have a value are omitted rather than present with a null value.

e.g.

{ "id" : "5652963" }

is preferred over

{ "id" : "5652963", "name" : null }

By default, Jackson includes null valued properties in serialized output but this can easily be changed using @JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL).

I believe this annotation should be used by default, my guess is that most JSON users prefer the lighter/cleaner format. If required, I'll add a parameter to allow this to be removed though, for those that want to see the nulls.
