Sockets and MQTT now on Espruino!

Here is a message I got from Wiznet, looks like the W5500 is the more modern chip. Shame there isn't a small module.

Dear Martin Honeywill,

Thank you for your request. You can see a quick overview of our chips
at thie link:
http://eucache.wiznet.co.kr/sub_modules/en/product/Product_Line.asp?cate1=5&cate2=7

The W5500 has been released last year and is our recommendation for
new projects. It is our most stable and cost optimized chip. In case
you want to evaluate our chip, we can recommend to start with the
WIZ550io module - http://wiznet.eu/WIZ550io

At the moment we do not have any small footprint module like the
WIZ820io - it is also not planned at the moment - the WIZ550io is not
as small as the WIZ820io, but hopefully small enough to fit your
needs.

For any further information, please don't hesitate to contact us via
support@wiznet.eu.

Best regards, Felix Krieg
