Who wants to update rails?

[John Eckersberg]

We're still running on the 3.2.12-ish stack that I put in after the
first round of security holes came through.  There's been several more
rounds and probably more to come, so we need to keep pulling in updates.
I just took a brief stab at updating to 3.2.12 proper, and a bunch of
tests exploded as usual.  I don't have time at the moment to bang on it
myself, so if anybody wants to jump on it, you can be a hero.
