Implemented engine sound and 3d sound effects using OpenAL. Engine sounds are only played for the first two players in a game.
Added an icon to the Mac OS X bundle. The icon is a Toyota Celica model by Gaurav Nawani rendered using Blender 2.43. The license for the model allows use of it freely for non-commercial gains.
Put OpenAL and ALUT frameworks into OS X app bundle. Current version of OpenAL has a bug in it which causes a memory freeing error when calling alutExit. Hopefully this will be fixed for next release.
