Existing chain that is shorter is still matched against the received
in order to avoid storage duplication. Data is also placed in FIFO
toward cliet (receiver side) before it is matched (may reduce latency).
Tray icons introduced instead of forms.
Bread after one chain is found on receiver side
Some logging modifications
Server side connection failure detection method is replaced by
disconnecting on exceptions in Rx methods on server side handlers
some improvements (reprocess pending data message before transmit),
statistics calculation...
