* Fixed namespace issue when decoding CAS-server response.
See https://github.com/chdemko/joomla-external-login/issues/12.

* Hard-coded HTTP instead of HTTPS CAS-server login url due to local cas-server problems. This should really be a configurable setting.
See https://github.com/chdemko/joomla-external-login/issues/11.

* Forcing cascading CAS-server logout without requiring the auto-login "feature".
See https://github.com/chdemko/joomla-external-login/issues/7.
ExternalLogin now honors the redirect-url in its menu item configuration after a successful login even if there was an http referrer.
The caslogin plugin accepts redirect-url entries that redirects off-site while still logging in the user first.
Fixed bug where the caslogin plugin would effectively authorize the request for user.login based on the redirect-url. Since the user is not yet logged in at that stage, restricted urls were not possible to use as redirect-urls.
