Missing overridden method JsonMergePatch.toString()

[jesperdj]

When I call toString() on a JsonPatch object, I get the patch in JSON format as a string.

When I call toString() on a JsonMergePatch object, I get: org.glassfish.json.JsonMergePatchImpl@47c62251

It looks like the implementation of JsonMergePatch in the JSON-P reference implementation does not have an overridden toString() method, which seems inconsistent.

Please override toString() in the implementation of JsonMergePatch to return the patch as JSON.
