--video-file command line option do nothing

[goatscrub]

Hi again :)

--video-file option with argument don't load file into player without error.
It seems there is not really code to load the video into player.
I fixed it with a uggly solution again into gaupol/_init_application.py:

             application.update_gui()
+            application.load_video(path)

I understand that is not the good way.

Thanks.
