Make sure running works as intended with Grunt 1

[kokarn]

There are some awesome improvements coming soon, we should make sure they work as intended.

The main part i'm worried about is using grunt without grunt cli but this in package.json

"scripts": {
  "grunt": "grunt"
}

Yes, we need to start preparing the code for that configuration method.

Now that Grunt 1.0.0 is released this needs to be adressed.
Confirmed not working right now.

The expected behaviour should probably be to check if npm run grunt is defined before running grunt.
If it is, use that instead of just grunt.
Thoughts @ealves-pt ?
