Unable to Specify Alternate Log Handlers

[citruspi]

Users don't currently have the option to specify a log handler. While it's not important now, it would be useful to specify a handler to log to a file instead of printing to the terminal if the interaction with Tyr was being automated.

It will also be extremely useful when the project becomes a "hosted" service. It would be cool to be able to show users what's happening in real time. One option would be specify a log handler that streams the logs to a socket or an HTTP server with the end result being that the user can see the log statements as they get emitted instead of seeing a single dump at the end.
