First commit to ApacheUsergrid for new PHP5 sdks.

This is a new version of the PHP SDK for ApacheUsergrid. Its built with PHP Guzzle web service descriptors with versioned manifest files. As apache usergrid progresses its easy to add new api calls going forward. It also is built using current PHP design principles. It can be used in any php application but it is design to work out of the box with Laravel Framework or other frameworks like Symfony2 it has DI and use IoC. It contain service providers and Facades . Its like the AWS sdks where you can enable Facade and use the API using static Method e.g. ```Usergrid::management()->getApps()``` . It also has OAuth 2 auth flow built in with all levels so you can use client id or username and password and auth as user, application , organisation or organisation  admin user. It also has the option to turn off the Guzzle OAuth2 plugin and you can manage the oath flow yourself .. Its all in the README.md file and this is a PHP composer package so till its in it own Repo you can use my repo in your composer.json file so you can get started right away. ```https://apps4u@bitbucket.org/apps4u/apache-usergrid.git```
