For our primary measures of user engagement, messages sent by bots can
confuse the picture (e.g. a realm could be dead, but not appear to be,
because they didn't bother uninstalling their github and jenkins
hooks). So it's best to leave those out of our main stats.

They are more meaningful this way -- the fact that your bots that
never log in or inactive users don't have colored streams shouldn't
impact that statistic.
