Unmanaged libraries require a predefined target platform - todo:
dynamically load DLL files depending on platform
Goodbye NAudio - welcome SFML.NET

NAudio doesn't work on Linux, replaced it by SFML.NET (C/C++ library)
which supports a lot of formats and 3D sound. Todo: add MP3 support
Extended the SFML library to support MP3
This works in two ways: 1) by direct streaming or 2) by encoding the file to 32bit WAV on-the-fly and completely loading it into the buffer (not recommend). Fusee supports 23 formats now: mp3, ogg, wav, flac, aiff, au, raw, paf, svx, nist, voc, ircam, w64, mat4, mat5 pvf, htk, sds, avr, sd2, caf, wve, mpc2k, rf64
Added a warning when using mp3 - consider using ogg instead
Added all necessary shared library for Linux
Optimized using of ressources and extended WebAudio
> LoadFile now checks if a sound files has already been loaded and If so it copys the soundbuffer instead of loading the file again.
> WebAudio: SetVolume/GetVolume has been implemented
Added a "rolling" sound for CubeAndTiles
