Thread's functionality method.
The starting point for the thread. After calling start(), the newly created
thread calls this function. This function then tries to make QTcpSocket.
It waits `WAIT_TIME_MS` for an incoming message. If message is received
it checks its a whole message using blockSize sent in the first word as
an UINT16 number. If a whole message is received, the thread tries to execute
the message string and sends back an appropriate response. The response is
*Command failed - "error string"* if the execution failed, or *Command
executed successfully* otherwise. Then the thread is terminated.
