Upgrade rust-websocket, rust-openssl, and hyper

Upgrade `rust-websocket` to v0.20, maintaining use of its sync client.

This indirectly switches from `rust-openssl` v0.7 - which required
openssl-1.0 on all platforms - to `native-tls`, which allows for use of
schannel on Windows, Secure Transport on OSX, and openssl-1.1 on other
platforms.

Additionally, since hyper is no longer even a dependency of
rust-websocket, we can safely and easily upgrade to `hyper` v0.10 and
`multipart` v0.12.

This commit is fairly experimental as it has not been tested on a
long-running bot.
