Implement proxy re-configuration

- application level proxy is reconfigured on settings saving
- tested with direct connection (no proxy), local proxy without auth
  (tinyproxy) and SOCKS (ssh -D dynamic port forwarding)
- not sure about QNetworkProxy reuse between invocations
- consider using QNetworkProxyFactory (but since no plain TCP
  connections are used, QNetworkProxy seems to be good choice)
