    Patch to clear up defaults and description for mono-mixer UI
    
    From the GIMP UI it's very tough to tell what the values represent, so changing 'Amount of [color]' to 
'[color] Channel Multiplier]' will help understanding of what the UI is representing.
    
    To go with this, set default value to .333 so a default conversion is approximately luminosity neutral.
    
    Lastly, pull the value range toward a reasonable range -10 to 10 is extreme
