Gioacchino Mazzurco 953b70fbe4 Improve async distant chat, fix chat msg receiving
DistantChatService::initiateDistantChatConnexion(...) made notification
  message optional (enabled by default)
p3ChatService removed duplicion avoidance as it is not necessary
p3ChatService::sendStatusString(...) send status only if peer is online
protect p3ChatService::mDistantGxsMap with mutex as operation on it may
  be done by different threads
p3ChatService::receiveGxsMai(...) set chat message item peer id with
  distant tunnel id, so it is recognized as a distant message later
made p3GxsTunnelService::makeGxsTunnelId(...) static as it need no
  access to this, now it can be used easier by other components
rename RsGxsMailItem::recipientsHint to recipientHint as for now only
  one recipient is possible (TODO: update documentation too)
GxsMailsClient::receiveGxsMail(...) changed paramethers for better
  abstracion, now destination id is passed too because it is usually a
  very useful information
ChatWidget some adaptation to async chat, a couple of method have been
  deprecated too
PopupDistantChatDialog::updateDisplay(...) adapt message shown to the
  user to the new async chat paradigm (TODO: need review)
