p01-contact : simply add contact forms in your pages

[gimx]

Hello,

Suggestions for the next release of this excellent plugin

- Add checkbox in form "Send me a copy" or no checkbox and the plugin send copy at the sender automatically,
- Ability to customize the message after sending email (the page with the anchor #p01-contact),
- If no subject, the plugin should have a defaut subject like "Message from domain.tld" for example (no subject can redirect email in spam),
- Same suggestion with the name, not "Anonymous" but "User of domain.tld" for example.

That's all
