Add additional check for "REDIRECT_HTTP_AUTHORIZATION"

I am using PHP in fastCGI mode and HTTP authorization. I have added the .htaccess patch:

However, now the info is stored in $_SERVER['REDIRECT_HTTP_AUTHORIZATION'] instead of $_SERVER['HTTP_AUTHORIZATION']

I think this is a hoster related setup for cgi environments but many people like me could run into this issue.

see for example also:

https://www.drupal.org/node/2101361
https://github.com/zendframework/zf2/issues/5873
http://www.rosmir.org/Index/Docs/archive/LabsFolder/FastCGI

and so on.

So i would suggest to add the following in "function _services_basic_auth_authenticate_call":

// PHP FastCGI doesn't support HTTP Basic Authentication out of the box so we
  // need this workaround. Requires a patch to .htaccess.
  // @see http://drupal.org/node/1864628.
  if (isset($_SERVER['HTTP_AUTHORIZATION']) AND !empty($_SERVER['HTTP_AUTHORIZATION'])) {
    list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':', base64_decode(substr($_SERVER['HTTP_AUTHORIZATION'], 6)), 2);
  } elseif (isset($_SERVER['REDIRECT_HTTP_AUTHORIZATION']) AND !empty($_SERVER['REDIRECT_HTTP_AUTHORIZATION'])) {
    list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':', base64_decode(substr($_SERVER['REDIRECT_HTTP_AUTHORIZATION'], 6)), 2);
  }

Could you please add this into your module´s next release?! (And/Ord comment my suggestion and argument pro/cons) ?

Thanks!
