OAuth with Zend FW

I've made my Zend GData 1.7.3 installation work with OAuth
authorization, and I'd like to contribute it back to Zend. It's not
many changes - 2 member variables and setters/getters + 1
modification. I use http://oauth.googlecode.com/svn/code/php/OAuth.php
to get the OAuth-generated value of 'authorization' header - which is
under Apache2 license, so should be BSD-compatible - so we could have
a wrapper for it.

Added to library/Zend/Gdata/HttpClient.php:

        /** Value of 'Authorization:' header
        */
        var $_oauthHeaderValue= null;
        /** Value of 'xoauth_requestor_id' HTTP parameter that we append to
the request URLs. Not url-encoded, since
                HttpClient will encode it itself.
        */
        var $_xoauthRequestorId= null;
       
        public function getOAuthHeaderValue() { return $this->_oauthHeaderValue; }
        public function setOAuthHeaderValue( $value ) {
$this->_oauthHeaderValue= $value; }
       
        public function getXoauthRequestorId() { return $this->xoauth_requestor_id; }
        public function setXoauthRequestorId( $value ) {
$this->xoauth_requestor_id= $value; }

Modified in library/Zend/Gdata/HttpClient.php:
    public function filterHttpRequest($method, $url, $headers =
array(), $body = null, $contentType = null) {
        if ($this->getAuthSubToken() != null) {
             // curent code...
        }
        } else
                if ($this->getClientLoginToken() != null) {
            $headers['authorization'] = 'GoogleLogin auth=' .
$this->getClientLoginToken();
        }
                elseif( $this->getOAuthHeaderValue() ) {
                        $headers['authorization']= $this->getOAuthHeaderValue();
                }
                if( $this->getXoauthRequestorId() ) {
                        $param_pair= 'xoauth_requestor_id=' .urlencode(
$this->getXoauthRequestorId() );
                        $separator= strpos($url, '?')===FALSE
                                ? '?'
                                : '&';
                        $url.= $separator.$param_pair;
                }
               // current code...
