I created a modified version of this pull request. It does not yet register
any extra serializers, but it uses the tests to verify that extra serializers
work.
The reason I did not add any is that this is actually registers a small
subset of the types. JodaTime defines a gazillion types, which seem too many to
register all by default, and just picking two classes is intransparent.
To remedy that, should we offer an API util where you can call
`SerializerUtil.registerJodaTimeClasses(env)` or
`SerializerUtil.registerJavaUtilClasses(env)`.
In addition, we could offer to register select classes from the set of
classes/serializers known there by calling
`SerializerUtil.registerSerializer(class)`.
