[meta] Modifications to the Honeypot form element

There are a number of open issues related to the structure of the Honeypot form element. Because this form element is really the heart of how Honeypot works, and because each of these issues changes some part of that element, I think we should have a place to discuss the big picture. Hence this meta.

I also think if we make significant changes to this element we should make them in a new minor point branch, because these changes will be affecting the markup and therefore may potentially break sites which rely on the old markup. Additionally, because all of these issues affect the same block of code, all the patches in these issues conflict with each other.
