eslint breaking the build

eslint is breaking the editor build. I've commented eslinted out in `Gruntfile.js` for now so the build works. Below is the error I received in the terminal while running it:

```bash
Aborted due to warnings.
npm ERR! code ELIFECYCLE
npm ERR! errno 3
npm ERR! bramble@1.9.0-0 build: `grunt build-browser`
npm ERR! Exit status 3
npm ERR!
npm ERR! Failed at the bramble@1.9.0-0 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

If you could take a look at it @twigz20 that'd be greatly appreciated. Thanks!
