FS#103 - Use OpenAL

SDL_mixer is great and all but doesn't provide great features relating to spatial 3D sound positioning.

Mix_SetPosition and Mix_SetDistance can do the job but involves more effort on our side, and generally isn't really fit for 3D audio.

OpenAL is as cross-platform as SDL_mixer coupled with SDL_audio, if not more efficient as it is an OpenGL-like standard allowing for different system implementations, and OpenAL Soft which is almost the only implementation used supports many sound systems, is made from the ground up for 3D games, and even provides advanced features such as EFX (reverb, absorption) or HRTF.

If needs be the audio system can be made backend-agnostic using virtual classes, so we keep SDL_mixer if necessary.
