AudioBookConverter - Version 2.x: Performance

Version 2.0

Reverse engineered the product while keeping most of original archtecture and optimised most visible bottlenecks:

• major change - parallel processing of all files in the book and merging them at then end (which on my 24-cores workstation gave huge performance gain)
• moved away from java decoding of mp3 to ffmpeg
• played with and then replaced faac with ffmpep
• removed all 3rd party java libraries dealing with medias
• initial chapter support based just on source files
• added/removed/added again MP4V2 (built from latest source) to support artworks
