FavIcon Proxy

Favicons are now proxied through the Vade server which reaches out and
finds the icon to display it.

Icons are collected via either rel="icon" or rel="shortcut icon" or
/favicon.ico.

This should allow favicons to be used more reliably and bypasses CORS
mechanisms.

Healthcheck was also increased to 5 minutes from 1 minute.
