Subject: [PATCH] Return 0 instead of -1 on
 enet_protocol_receive_incoming_commands

Return 0 instead of -1 on enet_protocol_receive_incoming_commands when nothing received.
This allows the Service loop to continue running and not return an error when there is nothing to do with the socket receive.

From debugging I found sometimes the enet_protocol_receive_incoming_commands returns -1 because simply nothing happened in the 256 for loop.

Other functions like enet_protocol_send_outgoing_commands return 0 when nothing happened.
