Update all vendored deps (glide cc && glide update)
Update all vendored deps (glide cc && glide update)

A new dev cycle means it's a good time to update. I had to remember
to clear my glide cache before updating due to a long standing bug
(see: https://github.com/Masterminds/glide/issues/592).

I was definitely motivated, to see if we can benefit from first-class
middleware support in `gorilla/mux` (see:
https://github.com/gorilla/mux/issues/293).
