I would suggest to add some more serializers from `de.javakaffee` .. since
we have it already as a dependency, it doesn't hurt to add them.
I'm suggesting
- `jodatime/JodaIntervalSerializer`,
- `guava/ImmutableListSerializer`,
- `UnmodifiableCollectionsSerializer`,
- `GregorianCalendarSerializer`,
- `EnumSetSerializer`,
- `EnumMapSerializer`,
- BitSetSerializer - serializer for java.util.BitSet
- RegexSerializer - serializer for java.util.regex.Pattern
- URISerializer - serializer for java.net.URI
- UUIDSerializer - serializer for java.util.UUID
