Splitting out some of the bot functions into a library will make it easier for heavily customized bots to have their own version of run.py, instead of the shared one that we use for everyone now. If they use bot_lib.py directly, they will still most likely conform to the "Handler" interface as long as they call run_message_handler_for_bot. Most bots should continue to use contrib_bots/run.py for now.
