Use Guzzle\Service\Client as GuzzleClient

Use Guzzle\Service\Client as GuzzleClient to prevent name collision:
Fatal error: Cannot use Guzzle\Service\Client as Client because the name is already in use
Bumped the requirement on PHPUnit to 4.0, and added status as a field in some of the response models
Fixed a possible naming collision with the old version of the client that was called Client
Added some tests for the getPublicKey and getImageIdentifier parts of the URLs
Added support for fetching the public key and the image identifier from the URL instances
Removed the short URL tests for now
Added a command and a response model for adding short URLs
Renamed the getShortUrl method to generateShortUrl and made it work with the way Imbo now handles short URLs
Keep the getShortUrl method
