First working version of grunt-cli like wrapper

The use cases for this are:
* When run from a global context
  * Support only the 'create' command
  * This will create a directory, npm init, npm install cordova
  * Then forward to cordova-cli the original create arguments
* When run from a local context (i.e., inside a cordova workspace)
  * Find the local cordova npm installed version
  * Forward the command line arguments to that
