Disable some inapplicable controls. Include dither miss in random walk accumulator.
Cleanup of the previous dither MR.
- disable the max-iterations dither option when one-pulse is selected, as it doesn't apply
- disable some PHD2-only controls when PHD2 is not being used.
- change the label on those PHD2-only controls to indicate PHD2
- For one-pulse dithering, include the miss in the dither in the accumulation of dither random walk.
