ChangeLog: 

Implement more of XEP-0065 to support sending files through a proxy. To avoid adding strings this close to a release, it only supports using a proxy that is discovered from the server, but we'll include an account option to manually specify a ft proxy in the next release. Lots of this is based on a patch from galt - Fixes #3730, #116, #1768
