Title: Add client_credentials grant type *updated

Allows a client to use client_id and client_secret to obtain a non refreshable access token:
http://tools.ietf.org/html/draft-ietf-oauth-v2-23#section-1.3.4

* Updated to accept Basic Auth to encoding of client_id and client_secret
* Code passes all tests in 1.8.7 and 1.9.3 (after bumping rspec)
* Has been running in a production environment for over a month with no issues
