Issue: [4.1 Alpha 1] Edit Widget: various wiki widgets don't show previously saved values in admin cp

Wiki: Live search
When editing the Wiki live search widget in the admin cp, the checked/unchecked state for each typechoice option is not reflected in the form. To clarify, the checked values are saved and reflected in the widget around the public site, just not in admin.

This also affects canfilter. For this field, the label text is showing as part of the checkbox name attribute. Was this intended?
Wiki: Recent activity
The checked/unchecked state for each feed_type option all default back to checked.

The value for rate defaults back to 60.

Wiki: Similar content
The checked/unchecked state for each similar_options option all default back to checked.

The value for max defaults back to 6.

Also affects posterinfo.

From the widgets checked, this issue seems consistent. It may apply to other widget types.
