If services response from embed.ly is gzipped, no providers can be found

This is an intermittent issue that seems to depend on what embed.ly is doing. I found that sometimes my site would have no embed.ly providers. Debugging through, I found it was because the response we were getting back from api.embed.ly/1/services was some kind of gibberish. It was perfectly fine JSON when looking at it in a browser. It seems the response is gzipped, and nothing was handling the decompression.

I saw this happen yesterday, but it cleared up on its own, so I wrote it off. It happened again today though, so it'll probably happen again.

There's two ways I see to fix this:

1. Send headers with the request to disable compression
2. Decompress the result when we get it
