Implement the reply confirmation for the started signal.
After qtcreator_processlauncher starts a new process
we connect to its started() signal and post a reply through
the socket to the LauncherInterface with the information about
the new PID. ProcessLauncherImpl now emits the started signal
with a delay, just after the confirmation has been received.
