V1.7.0

Update 1.7.0:

* Added command line option to allow self restarting if Bluetooth device
  becomes unavailable.

  Older versions had to end program execution because when a Bluetooth
  device becomes unavailable, it won't be available for the program even
  when that Bluetooth device becomes available again.
