Updated to the latest version of Commander.js and added alias support.

Made the following changes:

* Updated to version 1.1.1 of Commander.js
* Added the ability to use aliases by separating commands with `|` (see `test.options.command.js` for an example).
* Updated examples to reflect the updated functionality of commander-plus
* Removed build badge from readme that was pointing to TJ's branch/build

Unit tests have been updated to run successfully (and cover the updated functionality) and version has been bumped to `0.0.5` (no breaking changes). Modulus CLI has been verified functional using this updated version.
