js file directory and license cleanup: moving all of our code out of assets/js/libs (so it is only 3rd parties), into new util dir, and making sure all files there have correct license information
(and all are compatible with apache).  removed json-formatter / formatJson because built-in JSON works just as well if not better for our purposes.
remove the dev/ files (since we run require.js optimize we don't need that copy of original JS source), and fix some broken usages of old path to brooklyn files
