Initial 'grunt build' aborting due to warnings

[ryancharris]

After forking and cloning to my local machine I ran npm install, which worked. However, grunt build is aborting due to a missing node module while running the variables task.

cc: #107

What version of Node are you using?

[ryancharris]

@sfrisk Node v5.9.0

[ryancharris]

@sfrisk Upgraded to 5.9.1 and the build still fails

I think this might be fixed by a current PR, but let me double check.

ping @arschmitz

[arschmitz]

build for node 5.x is fixed by #154

[sfrisk]

Going to prioritize pulling in that PR for today's meeting

[sfrisk]

@ryancharris, we've pulled in the code that should fix this problem.

@sfrisk Works on my end. Built without any errors. 👍
