In various places, we build messages using `Sprintf` before passing them to `Notice()`. If we let `Notice()` do string formatting, we run the chance of having it try to format our already-preformatted text. If our text includes format references (e.g. `%s`), it would cause a problem (`%s(MISSING)`). One way to trigger it is to change the bot prefix from `!pm` to `%pm`. Doing so, `sendHelp()` would create some help message which contains `%pm` references. `Notice()` would then try to process them as well, leading to a bunch of `%!p(MISSING)m` in the final text.
