Title: upgrade gems

I was just going to upgrade Roadie (was seeing a strange problem that this might fix), but figured "what the hell, might as well try upgrades across the board". Also includes [the Rails security fix](http://weblog.rubyonrails.org/2014/11/17/Rails-3-2-21-4-0-12-and-4-1-8-have-been-released/).
