Synthesizer chorus setting increment

The Chorus tab of the Synthesizer dialog has some issues:

1. The "depth" setting on the synthesizer always starts with 0 when MS first loads, but the slider shows .80

2. The increment on the up/down arrows for both "depth" and "speed" is set for 1, which is the entire range of the sliders. They should likely be .1. This means the sliders will jump from 0 to 1 with nothing inbetween.

3. If I drag either slider to some other value, say .5 then click the up-arrow to increment the value, it will jump to 1.5 so the arrow on the slider is no longer visible. If I continue clicking up, the value just keeps going up. I suspect this should not happen as the slider range only goes between 0 and 1.

It was this thread ( http://musescore.org/en/node/10819 ) where I first noticed the issue
