Subject: v0.8

  - Fixed: infinite loop after buffering message
  - Fixed: corrupt packets after closing connections in the stopped state
  - Fixed: bug in mapping user numbers between afclient and afserver
  - Fixed: premature close of the service connection
  - Fixed: invalid buffering when the connection is closing
  - Added: Multiple tunnels in one afclient<->afserver connection
