This commit separates the types for interactive and non-interactive text within package widget. widget.Selectable is used for all interactive text. widget.Label is used for all non-interactive text. There is no longer a field on widget.Label to provide it with a Selectable. If you want selectable text and are not relying upon the material pacakge API, you need to create widget.Selectables instead of widget.Labels. The material package's LabelStyle API is unchanged.
