Log Hubot's built-in @Logger when requested

[saraford]

In hubot's code, there's a logger for things like info, debug, etc. When hubot is run via command line, you can specify this as an env variable.

Looks like the hubot @logger 'Log' calls are going to the Terminal and not the browser console. Looking into ways to re-log this information to the browser console.

If nothing else, I could print these out to a log file.
