updates to bot.js to support running under #qa channel with occasional test day events

I've been testing this on #testdaybotTest running on irc.mozilla.org. 
Enter :help for general help or /msg _TestDayBot :help (testDayAdmins only: ashughes, whimboo, galgeek for now) for test day admin help.
stats for now print to the console.
I think the 2 is still debug code.
