Wiznet Options and Special Build

Gordon

1. On http://www.espruino.com/WIZnet the link to the git builds doesn't work, sorry

2. Is there any particular reason for the choice of the WIZ550io module? Just wondering
   if http://www.shopwiznet.com/wiz820io might work as it's smaller. It's an older chip, but maybe the API is the same? (I'll check if you don't immediately know)

Thanks
