Witnesses: Temporary bug with hivefeed-js

Hello all hive witnesses!

Quick announcement for anyone using hivefeed-js as their price feed. You may have noticed that as of about yesterday, many of the price feeds went down. This is due to a bug in hivefeed-js right now being caused by the Ionomy exchange api possibly changing some of their endpoints and api functionality. This causes the hivefeed app to crash and no longer post a price feed.

I am currently working on a fix for this and will hopefully have it resolved yet this evening, and after that I will post a follow up announcement so that everyone knows to upgrade. In the meantime, you can hotfix this by putting "ionomy" in your config.json file where it says "disable_exchanges".

Hopefully will have the fix up soon here!

Best,
Sicarius
