Document Socks support

Also correct various Socks related types. This commit also
adds a new gun:protocols/0 type as a simpler way of describing
preferred protocols. The protocol/opts tuple is also documented.

This commit also fixes an issue with the default value for the
preferred protocols when using CONNECT over TLS. It was
mistakenly not enabling http2 by default.
