iojs.org doesn't support resumable downloads

[ljharb]

Run this command twice:
curl --progress-bar -L -C - https://iojs.org/dist/v1.0.1/iojs-v1.0.1-darwin-x64.tar.gz -o /tmp/iojs.tar.gz

The first time, it works just fine. The second time, the -C - should tell curl to try to resume the download, and since it's at 100%, it shouldn't download anything. Instead, I get curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.

gzip disables ranges support inside its server/location section (here's why). One possible solution would be to put the big files inside its own location section with gzip disabled. Will do a PR.
