improvements for examples

[FreCap]

how is it possible to certificate your identity without have logged in? so in examples/server/lib/actions.php on line 41 we should replace with this code:

if ($request->idSelect()) {
            // Perform IDP-driven identifier selection
            if ($request->mode == 'checkid_immediate') {
                $response =& $request->answer(false);
            } else {
                if (!getLoggedInUser()) {
                    return login_render();
                }
                return trust_render($request);
            }
        }

Moreover I don't understand why if you are logged in you have to provide your identity throught in trust.php so I replaced the function:

function trust_render($info)
{
    $current_user = getLoggedInUser();
    $lnk = link_render(idURL($current_user));
    $trust_root = htmlspecialchars($info->trust_root);
    $trust_url = buildURL('trust', true);

    /*if ($info->idSelect()) {
        $prompt = id_select_pat;
    } else {
        $prompt = sprintf(normal_pat, $lnk, $trust_root);
    }*/

        $prompt = sprintf(normal_pat, $lnk, $trust_root);


    $form = sprintf(trust_form_pat, $trust_url, $prompt);

    return page_render($form, $current_user, 'Trust This Site');
}

consequently in file common.php in the function doAuth I changed in this way;

 if ($info->idSelect()) {
        $req_url = idURL($user);
        /*
        if ($idpSelect) {
            $req_url = idURL($idpSelect);
        } else {
            $trusted = false;
        }*/
    } else {
        $req_url = $info->identity;
    }

I hope to be helpful!
