Centralise creation of MetaBean in XML parser
Handle type renames in deserialization

Fixes #40
Ensure XML reader property closed

Also use Class to cast object rather than suppress warnings

The list of known types should be close to that of Joda-Convert
Remove encodeClass/decodeClass from main serialization API
