Poor Mbot needs updates and unit tests

He wants to run on node 0.12, which is absolutely ancient.

I got him running on 4.9.1 with some errors in the npm i output - but still got it working. Then decided to "do it live". But yea, based on what I just went through this repo needs updated for sure. I'll let somebody else tackle that though.
