Feature request: Start vokoscreen from the CLI

[waterkip]

I'd like a way to start a recording from the command line. This would require command line switches to enable/disable features/options. But to get the ball rolling, I'd like to have the following options available:

vokoscreenng \
  --full-screen [optional screen id] \ # Depending
  --countdown 3 \ # or
  --no-countdown \ # This negates countdown
  --microphone [optional microphone id]\ #
  --no-microphone \ # default
  --config /path/to/config \ # default pick a configuration that has the above flags set already
  --record # finally, give the command

Alternatively:

vokoscreenng record --all-the-options from the previous example

Command line switches override the configuration.
