Initial commit

Browse source 
added libraries:
opus
flac
libsndfile

updated:
libvorbis
libogg
openal

- Everything works as expected for now. Bare in mind libsndfile needed the check for whether or not it could find the xiph libraries removed in order for this to work.

** ****************************
**
** How to use:
** - libsndfile.dll must have already been compiled and be in this

**
** - You must edit this file to point to the file you want to convert. Set
** the following line of code (found in the Main() function further below)
** to the name of a .WAV file that exists on your system.
** 186: string sfn = "input.wav";
**
** - From a command prompt type
** csc generate.cs
**
** - Run the resulting executable 'generate.exe'
**
**
** Note: You will obviously need the csc compiler and the .NET runtime. I think
** these are freely available for download from Microsoft's website
** (part of the .NET SDK?).
