Subject: v0.7.2

  - Added: http proxy basic authorization
  - Fixed: logging initialization after some value checking
  - Fixed: auto-reconnect failure when --nossl option is set
  - Added: auto-reconnect when afserver is not reachable on start
  - Added: auto-reconnect after normal afserver quit
  - Added: per user statistics: idle time, amount of downloaded/uploaded bytes
           and current download/upload rate
  - Added: support for https proxies
  - Added: possibility to bind sockets on different interfaces
  - Fixed: receiving incomplete headers from afclient
  - Fixed: close user connections by afclient
