[Plugin: Contact Form 7] Autoresponder, onsubmit hook, and mini-ticket system

1. Autoresponder – Auto Reply to sender, provide field in admin panel
2. Onsubmit hook – provide field in admin panel where to insert php code, which will be runned after sending. eg create page for customer with his name, email, id, etc for e-commerce.
3. Mini ticket system – besides sending the mail, all messages are available in a list in admin panel, and can be read
