5.0.0.31 (Aug 9, 2013)

Juno 5.0.0.31 is a moderate update.

- Simplified the {@link oaj.serializer.Serializer} and {@link oaj.parser.Parser} class hierarchies.
  This reverses a previous change that added a bunch of interfaces in these APIs (and subsequently required compiling with Java 7 to get around a compiler bug).
  The new class hierarchy is much simpler to understand.
- Added {@del oaj.transforms.XMLGregorianCalendarSwap} to convert these to ISO8601 strings during serialization, and vice versa during parsing.
- Added a strict mode to {@link oaj.json.JsonParser}.
- Added default {@link oaj.json.JsonParser#DEFAULT_STRICT} parser.
