CAPTCHA references update

I've updated the CAPTCHA draft with references converted to W3C format:

http://w3c.github.io/apa/captcha/

The features of Specref, which we use to structure references, don't 
fully support the style that was in the doc. Issue numbers for journals 
and edited collections aren't supported, so I did the best I could. DOI 
are also not supported; I put them in the source but it's not being output.

I haven't comprehensively checked, but I think many of the references 
defined are not actually referenced in the doc. They will only show up 
in the appendix if there is a reference to them, so additional pointers 
may need to be added.
