Review: Further enabled the NukeWrapper for channel swizzling

Sean Looper <sean....@...>

Fixed some misspellings and re-enabled all the NukeWrapper features, redoing the knob layouts. I did remove some knobs rather than use the ObsoleteKnob. Wasn't sure if that was necessary yet. If it is, I can revisit. It doesn't hurt anything, but it does scare users when Nuke warns them that it can't find a knob for a knob value.
