ZF-9284: Enable 2LO by making oauth_token optional in Zend/Oauth/Http/Utility.php


In 2-legged OAuth, the oauth_token is not used-- requests are made purely based on the consumer key/secret. Suggest adding a check to Zend_Oauth_Http_Utility::assembleParams so that the oauth_token value is only sent if non-null.


Attached patch modifies Zend_Oauth_Http_Utility::assembleParams to make the oauth_token param only set if non-null

Implemented in r21232 and merged to release-1.10 for next mini-release. Thanks for the patch!
