Add jsonify method

In the doJsonify method, I changed the approach to using a StringBuilder to store the results instead of the Map itself.

And hopefully I got the launch files they way they used to be... I cloned from Cinchapi then copied and pasted over my local files.

You can define a new static instance of this function in the `org.cinchapi.concourse.server.storage.Functions` class. Something like `TOBJECT_TO_JAVA` because it seems like something we might want to reuse again. Not necessary, but its a nice code refactoring if you ever get a chance to do it
