Included the checkstyle reporter in the bundle so that it can be used in rhino environment. Also updating the gradle-js-plugin so that jshint can be used to generate checkstyle reports to be parsed by jenkins after builds.

Made minor change to the checkstyle reporter to be able to print instead of using process.stdout. 

Had to create a fake console to handle error prints from the event package about event listener memory leaks, because listeners doesn't seem to be removed when too many files are given as input to jshint. That issue needs to be addressed by someone who knows how.
