ircbot: Make #fedora-design bot emit more useful messages

I was trying to meet this criteria for the filter. I used the CommOps
and Badges bots as examples to figure this out:

[12:20:02] <mizmo> when someone posts to the list - very helpful
[12:20:14] <mizmo> when someone files or coments on a design ticket - very helpful
