Shawn J. Goff 6a18f59532 Change name of icanhasall to subscribe_to_all
icanhasall is cute (for now), but the effect of the variable is clear
only after tracking down its origin reading the commit. This change is
intended to make it easier for people to have some intuition about its
effect from its name.
