Fixed the bundled ruby-openid gem

* The open_id_authentication plugin will require the gem automatically so
  it doesn't need to be added to environment.rb
* Changed the version requirement on the open_id_authentication to match
  the latest stable version.  Rails config.gem looks for a directory named
  after that specific version and will not load newer versions.
