[PEPr] Changes in proposal for Web Services::Services_RackCloud

Josh Kendall (http://pear.php.net/user/jtkendall) has edited the proposal for Web Services::Services_RackCloud. Change comment: Per suggestions in the comments I've updated the code to allow Services_RackCloud::setFormat() to accept JSON, XML, Object, and Array as valid formats. If JSON or XML are used the response will be a string (useful for variety of projects such as those using Flash as a frontend). Object returns an object containing an array of objects, and Array returns a multidimensional array. The example.phps file has been updated to reference these changes. I've also updated the comment for Services_RackCloud::setFormat() as it incorrectly suggested that the format set was the format to be used for responses and requests, where it's actually only the response format. All requests are sent as JSON, hence the reason why the JSON extension is still a required dependency. Please review the proposal: http://pear.php.net/pepr/pepr-proposal-show.php?id=630
