Spamtastic

Okay, so yesterday my comment spam went absolutely mental. Literally one every couple of minutes for half a day. Total pain in the ass, so I've had to implement a captcha, unfortunately a necessary evil. I also chose to implement a slightly different to normal captca in the name of reCAPTCHA.

Basically it gives you two distorted words, the first is a word from some book digitization process that couldn't beOCR'd the second being a word that is known. By getting the second correct, reCAPTCHA uses your interpretation of the first and contributes it back to the digitization (once verified a few times by others).

Little more work than normal but seemed like a good cause and makes a good use of those few extra seconds.
