this line is still too long :)

You should install jshint on your computer. Since we require at least version 2.4.2, the easiest is probably to just link to the one in "node_modules" that you probably already have.

* To know if you have it: `ls node_modules/.bin/jshint`
* To install all dev dependencies: run `npm install` or `npm install --dev` (I never know which one we need)
* Then make a symlink to `node_modules/.bin/jshint` in a directory that's in your patch (on my computer `~/bin` is in my path, so I just did: `cd ~/bin && ln -s <gaia dir>/node_modules/.bin/jshint`
