Added LogDebug

[kennedy]

resolves #282
This provides basic situation awareness of the bridge. Created a new logging method called LogDebug for legitimate verbose debug messages. Bonus, I created a plain log message type without any prefix or flags for the version info.
UPDATE:
I also changed the log variable from debug to logger

-debug=false or omitted

Yay, this is awesome! ❤️ I will love to have this in logs, especially like on days like today when there are major infrastructure outages (looking at you, OVH) and some of our bots stop working for mysterious reasons.
