[Buildroot] [PATCH] docs/website: fixing query.yahooapis.com shutdown

[Angelo Compagnucci <angelo@amarulasolutions.com>]

This patch rework the use of query.yahooapis.com to do the conversion
from xml to json required by our script and moves to the use of a js
library. Datas are therefore now converted in json format on the client.

Unfortunately, cause of the CORS restriction on nabble and
buildroot.org, we cannot retrieve directly the xml data from these
servers and we need a CORS proxy to do that.

I'm in contact with anbble system administrator to give us access to
cors request for their mailing archive so hopefully we can remove the
call to an external service in a not so distant future.
