Handling Multiple Languages

[florisre]

Current behavior: language set to en gives me the English output for a video and fails if there are no English subtitles.
Behavior I would prefer: language set to en,de,fa gives me the subtitles in the first language where they are available. Fails if none of the languages are available.

Why? Currently, I have to go to the plugin's settings over and over again to get subtitles from videos in different languages. I'd prefer setting this up once and forgetting about it afterward.
