Cleaning up code, make everything runnable again.
Fixed eyed3 changes. (eyed3.core.foo instead eyed3.foo somewere)
Non-debug is cleaner. (Less spamy, and now is an option in the config.json file)
File scanning is now working again. (I swear this did work. Maybe not uploaded, now lost, work?)
New Algorithm to find the next tracks, now with 20% less infinity. (recursive calling could happen to never end...)
Added files/structure for future web UI changes. (FontAwesome is - well - awesome!)
