v0.0.2

This release allows functions to be passed as cmd, in addition to strings and arrays. It also allow matrix targets to be the cmd to run. I.e.

matrix: {
  'v0.10': 'codeclimate < coverage/coverage.html'
}

It allows the same types of parameters: string, array, and function.

Finally, this release adds a force option to prevent the grunt task chain from failing on non-critical tasks.
