21.0.490

Add proper update behavior for setting values with the channel widget for the config controls in the rig state. Add option to use action buttons in the channel widget. All button controls that set string values will automatically get such an action button. e.g. all of the config controls that set tags in the Rig State. This way all the functionality of the controls can now also be triggered directly via the channel widget
