Adjust volume slider min/max values to match range supported by hardware
Jeffrey Lee authored
Detail:
  c/main, c/sound, h/sound - Now uses the additional gain data returned by SoundCtrl_ExamineMixer to alter the volume slider min, max and step values.
  If SoundCtrl_ExamineMixer doesn't return any additional gain data, the sliders will have properties that match those of previous versions of the plugin.
Admin:
  Tested on Iyonix & BB-xM, both with and without the new gain data being available.
  Note that a bug in previous versions of SndSetup will cause it to crash/malfunction if it encounters the new gain data (i.e. SoundCtrl 1.01+ used with a mixer device which implements HAL mixer API 0.1+)
