Version 3.2.0 of Rainbows!

Release Notes: IO#trysendfile in the sendfile 1.1.0 gem is now used to reduce the cost of generating backtraces for slow clients (from EAGAIN). There is nothing new for people not serving static files. Existing "sendfile" gem users must upgrade to 1.1.0 or risk being left without sendfile support at all.
