Blip buffer and Alure

Blip Buffer is a lib to do band limited sound synthesis. Here we are using it to generate squred wave  sounds, but could be used to synth more complex and rich sounds like the AY-3 chip or other old computer and 8-bit game consoles.

Alure is a wraper lib over OpenAL, that makes more easy to initialize it, load sound assets, and play audio streams. Currently ALURE includes a basic .wav and .aif file reader, and can leverage external libraries such as libSndFile (for extended wave formats and several others), VorbisFile (for Ogg Vorbis), FLAC (for FLAC and Ogg FLAC), and others. External libraries can also be dynamically loaded at run-time, or individually disabled outright at compile time.
This could be considered as a little test for his use in Trillek game engine.
