Parameter adjustment enhancement

[jamescarruthers]

Use shift and click on the increment controls to adjust the amount it adjusts.

For instance if decimal is set to 3, then a normal click = +/- 0.001 and a shift click = +/- 0.01. Bonus points for adding control click to do +/- 0.1.

For non decimal, maybe shift click = +/- 10, and control click = +/- 100.

A better way of putting this;

Shift-click = increment by 10
Click = increment by 1
Control-click = increment by 0.1

Unless decimal is set, in which case increment by ten times the decimal, the decimal or 1/10th the decimal for shift, normal, control respectively.
