Replace Sox with managed libraries

[villermen]

Naudio.Vorbis should be able to do whatever it is Sox is doing right now without requiring it to be installed separately. Saves an additional dependency and probably allows for more control at the same time too!

Mejrs: I guess I got it to work with Sox, although i really did not want to add a dependency that users need to install
Villermen: Sox portable can be dropped in I believe, but I get the concern. Same with how I try to pack in all other dependencies right now. I could probably run the decode/encode process via NVorbis/NAudio too if I invest some time (like a weekend). Whatcha working on?
