Refactor Json serialization classes so they share a common interface and factory as the java serialization.

[GoogleCodeExporter]

The goal is that all code uses the same Reader and Writer interfaces to
serialize a instance to json and vice versa. Annotations would still be
used to map json properties <-> java fields.

The only code that would be different is the initial method which will
prolly still use deferred binding to return a SerializationFactory
instance. From the SF users can create a Reader or Writer as per their needs.

Both forms of serialization ultimately serialize objects into a string,
there fore the result of a Writer can be accomodated by a common interface.
The same is also true of a Reader which takes a serialized form of an
object stream and returns Objects in reverse to a Writer.

JsonSerializers instances which currently serialize and deserialize to and
from json would need to be refactored to match the new interface definition
of rocket.serialization.Serialization module.
