Feature: Add large slider popup

[mrariden]

It can be helpful to have more range on the slider to get the viewer saturation just right. Added low/high textboxes as well. The textboxes and slider all validate user inputs.

The popup opens with right click and is attached to the slider that was right-clicked.

Rewired the signal passing between the sliders to make it more extensible for future changes with arbitrary channel colors.
