* Added --help and -h command line options which print the available options

and quit the program immediately.
* Added --deskbar option to automatically install the Deskbar replicant.
  NetworkStatus waits up to 10 seconds for Deskbar to become available in
  case it is not running. In case the replicant is already installed, the
  program quits immediately.
* Refactored a _InstallDeskbarReplicant() method.
