Add option to always open video files in external players

### Short description

Please add an option to always open video files in an external player.

### Long description

At the moment, when I click on a video in the Beta app the app starts streaming the video in the internal player. This is OK for people that don't have any good external video players. However, there are a lot of people that have very advanced external video players (with brightness control, swipe navigation, etc.), which support much more formats than the internal video player. For those people it would be nice to open the videos by default in the external player, since the current solution by long pressing the video, going to the context menu, and choosing "Stream video file in external player", is really time consuming and unnecessary.
