Aggressive honeypot

Backup of my experimental code for a more aggressive honeypot. (against 6.x-1.x)

This code ran in production for a couple of months, with varying results. Unfortunately, I didn't have time to analyze the (separately) recorded results, so I don't have any numbers and facts to share.

A word of caution though: Any attempt like this fundamentally means to deny any posts from visitors having JS disabled.

I tweaked and played with this code a lot, so it contains quite some "over-engineering" and commented out stuff right now ;)

Actually, on a second look, this is even my latest "advanced testing" variant that had the pure purpose of recording results without blocking any posts at all. (i.e., "dry-run")

Do NOT apply this patch.
