On retries limit exceed, reconnection to next node is performed.
Added to HandleConnection, HandleDisconnection, HandleRetry logging information about endpoint connected with each event.
Added guard to prevent connection to node itself when it persists as the last node.

Logger checks whether socket still exists when printing info about endpoint.
EnsureConnectionToAppropriateNode and PropagateToNetwork are extracted to one method - TransmitToNetworkIfAppropriate.
First node becomes network founder.

Removed checkbox indicating founding network from GUI.
