Allow to add more fields in the petition and to select which to use per-petition

[fallen]

For instance have a finite set of available fields like:

• first name
• last name
• phone number
• age
• nationality
• gender
• address
• Country
• zip code / postal code etc

And allow to select which field you want to appear in your petition.

Hello, ++1 on that one. This would be a must have for me. If you implement this, don't forget the zip code (code postal). Thanks !
