Login errors and deprecated functions

This plugin needs an update. Specifically the wpcas.php file. Line 91 should be changed to public static function authenticate() { instead of function authenticate() {, and line 99 should be changed to if ( $user = get_user_by( 'login', phpCAS::getUser() )){ // user since get_userdatabylogin() is deprecated.

There are also a couple of warnings / notices when logging out, but those two should definitely be fixed because the error messages actually prevent login.
