A couple of strings have been reversed in request_form.php. Also I have lengthened the shortname field.

Currently reads:
$mform->addElement('text', 'fullname', get_string('fullname'), 'maxlength="254" size="50"');
$mform->addRule('fullname', get_string('missingshortname'), 'required', null, 'client');
$mform->setType('fullname', PARAM_TEXT);

$mform->addElement('text', 'shortname', get_string('shortname'), 'maxlength="25" size="25"');
$mform->addRule('shortname', get_string('missingfullname'), 'required', null, 'client');
$mform->setType('shortname', PARAM_TEXT);

Should read:
$mform->addElement('text', 'fullname', get_string('fullname'), 'maxlength="254" size="50"');
$mform->addRule('fullname', get_string('missingfullname'), 'required', null, 'client');
$mform->setType('fullname', PARAM_TEXT);

$mform->addElement('text', 'shortname', get_string('shortname'), 'maxlength="25" size="25"');
$mform->addRule('shortname', get_string('missingshortname'), 'required', null, 'client');
$mform->setType('shortname', PARAM_TEXT);
