RS5k manager: Improve control behaviour of parameters with bigger range

[IOphonics]

Try to manually drag the 'Tune' parameter down one or two octaves and you'll probably notice a problem (assuming you have the script docked to the bottom as I do). As soon as you'll reach the border of the screen the parameter stops moving. Can you change that? Sure, you can always right click and type if you want a specific big parameter jump, but for rather sensitive parameters like pitch or filter frequencies it's much better to have a continious controller.

It seems a Reacript limitation, Cockos probably can fix that on their side.
