Investigate why app reaches out to refresh queries outside of 1hr setTimeout function.

Look into setting setInterval instead.

Console log from an overnight run shows that the update mechanism is firing all over the place. API providers will not appreciate.

Updated in lasted dev train and release 1.1.0.

Issues:

1. moved code from node_helper to MMM-Surf.js to update per client.
2. Noticed condition that would cause massive triggering of legacy code by multiple clients (e.g. electron Browser opening on screen and web client.

Testing so far (~48 hours) shows code update has addressed both. Will continue to monitor.
