Enhanced file renaming, more tokens

Created by: thomas-schultz

I've made small changes how the renaming handles the tokens. My goal was to keep all existing tokens and their functionality, but add more options especially for Audio-Tags like language, codec, channels, etc. I personally need these tags to distinguish between same movies/episodes with different languages. I did a little bit of testing, so for me it seems to work, but overall i have probably overseen some edge cases.
