Video-settings (videodevicepool): do not save device automatically when open() is called with a device parameter
Video-settings (videodevicepool): do not save device automatically when open() is called with a device parameter

With the current code, always the last selected device is saved in the video-settings-dialog, even if the settings-changes are cancled/not applied.
Restoring the initial value in the settings-dialog would be very complex and video-settings should only be saved by calling videodevicepool::saveConfig() explicitly.
