Add jscs code style checker configuration
Add jscs code style checker configuration

Our JS code should follow a consistent and commonly accepted code style.

JSCS [1] is a code style checker for JS that can be integrated with the
WebStorm IDE and Grunt build. This configuration is based on a preset
for the Google style quide [2], with some exceptions and additions.

I suggest that we evaluate this setting by trying to apply it to our
code base and enable the grunt checks when we're comfortable with it.
