settings

 When using a [http://xmpp.org/extensions/xep-0065.html SOCKS5-bytestream
 (XEP-0065)] based file transfer, the account proxy settings are not
 considered at all, a direct connection to the other party (which may be
 either an intermediate server or another end user) is always performed.

 This ends up being somewhat confusing because the functionality re-uses
 the core libpurple SOCKS5 proxy functionality.  What is needed is to first
 connect to the account proxy (if any) and then perform the XEP-0066 SOCKS
 negotiation.
