[offlineimap] open_socket() leaks DNS requests when proxying (#189)

socks.setdefaultproxy() has a fourth arg for sending DNS requests through the proxy
https://github.com/OfflineIMAP/offlineimap/blob/master/offlineimap/imapserver.py#L119

However, even with that fourth arg set to True, using getaddrinfo() bypasses SOCKS5 proxy for dns resolution. This also breaks .onion Tor hidden service resolution.

Might consider socks.wrapmodule().
