[PROPOSAL] Add ReplyTo Email Address

[clemsy]

For a general contact form,

in MainController, action Index

                if(!is_null($mail_owner)) {
                    $ownerMail = $mailer->compose($mail_owner, ['model' => $form, 'params' => $params])
                        ->setSubject($form->getSettings()->mail_subject_owner)
                        **->setReplyTo([$form->email])**
                        ->setTo($form->getSettings()->mail_to);
                    // Save owner mail
                    $this->saveInDb($form, $ownerMail);
                    // Send owner mail
                    $ownerMail->send();
                }else{
                    $this->saveInDb($form);
                }

Would be a great improvement ?
