Updated PHP 5 client for Cloud Servers(tm) by Rackspace.

Just a quick announcement that I updated my PHP 5 client for Cloud Servers(tm) API.

Some of the major fixes include retry limiting for authentication requests, support for updated response codes (especially for server/image requests) and better examples.

Code was also updated to conform to PSR-2 and phpDocumentator 2.
