Turn on the last part of proposal 110
Tor 0.2.0.x is finally dead, as are the early, broken alphas of Tor 0.2.1.x. Let's see if we can enable the proposal 110 defenses at long last.
I'm targetting this for 0.2.3.x, but arma could easily convince me it was backportable to 0.2.2.x, so I'm going to base my branch there.
(I thought we had a ticket for this, but can't find it.)
