Move git folder to its own repo outside drupal.org and rename it to avoid confusion with git the version controller

Hi,

I have done some changes to this module code in response to the issue raise in http://drupal.org/node/1359162#comment-5530842 regarded to 3rd party code and the use of Libraries API for overcoming the issue.

1. I've created a repo at https://github.com/drupalista-br/Drupal-Google-Identity-ToolKit and moved the git folder into that new repo.
2. I've attributed the authorship of the code to easyrp, so if you create an account in github with that user name than all the commits will be attributed to you.
3. Advise me of you username at github so I can give you administrator permissions for this new repo I've just created.
4. In the patches that you will find attached to this thread, I've basically added the Library API 7.x-1.x dependency in the .info file and changed the way include_lib.inc is included in google_identity_toolkit.pages.inc which now runs through the Libraries API function in order to find the appropriate path to the external library.
5. I've also changed the README.txt and added the step-by-step installation process including how to install the external library (former git folder) which now resides at github.

Please dont forget to attribute the commit authorship by applying patches with

If you got any question please let me know.
