Print to file

[GoogleCodeExporter]

Currently, the script prints to stdout.
But redirecting output to a file produces empty output in file.

eg. rfxcmd -c -d /dev/ttyUSBx > /tmp/rfxcmd.csv
then, wait a while then Ctrl-C to exit rfxcmd.
the /tmp/rfxcmd.csv is a zero size file (even if frames have been received).

This is due to python buffered output.
To cope with this, buffer have to be flushed before exitting.

In shutdown() function, add sys.stdout.flush() call to force flushing.

def shutdown():
    # clean up PID file after us
    logdebug("Shutdown")
    if cmdarg.createpid:
        logdebug("Removing PID file " + str(config.pidfile))
        os.remove(config.pidfile)

    logdebug("Exit 0")
        sys.stdout.flush() <<<<<<<<<<<<<<<<<< code to add
    os._exit(0)
