Generalizes codesy addon so that an arbitrary set of sites can take the embeded form. Status of sites:
github: tested that it works as it did before..
mozilla: adds the codesy form to posts ('topic-actions' class)
betadata: my site, just has a stub at www.betadata.org/issues/ for testing
winehq: doesn't work, because winehq has a fixpng js error (for IE6 wtf?) that prevents embedded script from running
