Added --volume-step to override AOUT_VOLUME_DEFAULT. This will give an OSD menu (or skins2) designer to freedom to decide how many steps he wants for turning up the volume from 0 to 1024. It is an advanced option so most users will never see it. Can someone check the MacOSX changes for this? I made them but cannot compiler and test it (I don't have a Mac).
