Extract YamlJsonTranslator from StandardYamlCoder

Refactored StandardYamlCoder, extracting a new class, YamlJsonTranslator,
from it.  This facilitates performing yaml translation when not using a
standard "gson" coder.
Added YamlJacksonHandler which supports YAML translation layered on
top of a JacksonHandler instead of a GsonMessageBodyHandler.
Also added junit tests to complete coverage of StandardCoder.
Also added public APPLICATION_YAML to YamlMessageBodyHandler.
