Simplified and uniform volume handling: * Volume setting in dB on all targets, within the 'natural' range defined by the respective DAC (limited to -100..+12 dB for archos Recorders and Ondios in order to avoid 4 chars being displayed in the status bar). 0 dB means line level on all targets. * No more artificial volume limiting for Iriver and Player, settings always represent true values. Removed the various sound scaling options. * Bumped config version so save your settings. Also make sure to adjust the volume after loading a .cfg, then save the .cfg again, otherwise the volume will be out of range (a flaw in the .cfg loader).
