Disable websocket for updating data on the frontend

[lelleib]

It is necessary in my setup to make CumulusMX frontend avoid using a websocket connection (because I am using Cloudflare to make it available on the public internet).

I have found a way to do this by editing 'gaugefeed.js', 'dashboard.js' and 'now.js' in the folder /opt/CumulusMX/interface/js/ and changing the first line to 'var useWebSockets = false;'.

It would be nice to have this setting as some kind of configuration parameter. (And thus not to have to manually edit source code on every update.)

Thanks,
