aliasing any jcr-namespaced properties to fedora:

https://www.pivotaltracker.com/n/projects/684825/stories/83411334

any `jcr:` properties are transformed to `fedora:` before sending to the JMS broker.

This potentially causes **any** `jcr:` property to populate the `fedora:` namespace, which may not be desired.
Don't we have existing machinery for this? Can we use it?
