The Text Widget

A handful of new operations were added to the text widget. The dump operation provides a way to get all the information out of the widget, including information about tags, marks, and embedded windows. The mark next and mark previous operations let you search for marks. The tag prevrange is the complement of the existing tag nextrange operation.
