PHPCAS-90 Removed the $cookies parameter from readURL() since all cookie-aware requests now are in ProxiedServices.
PHPCAS-90 Removed the $cookies parameter from readURL() since all cookie-aware requests now are in ProxiedServices.

readURL()'s usage of CAS_CookieJar->addCookies() deviated from the method description
and causes problems when using the CookieJar as documented. This will be updated
in the next commit, but since readURL() doesn't need cookie support any more, I'm just
removing it.
