Closes https://github.com/rackerlabs/encore-ui/issues/319
`var moment = require('moment')` posts as a global var [in node environments](https://github.com/moment/moment/issues/1214), even if you write it out as `var m = require('moment');`. This confuses jshint since it sees a global var that, in its eyes, gets "overwritten" on require. If you change it to `false`, jshint will fail.
