CC-5709: Airtime Analyzer

* Added MetadataAnalyzer unit tests and test data
* Improved debug logging and squashed pika logging
* Implemented file moving
* Extract the track number/total
* Fixed mapping of mutagen to Airtime fields in a few spots. The mapping
  matches the DB column names now.
* Fixed the bin/airtime_analyzer binary
* Started work on PluploadController to make it work with the new File
  API
