Title: added `category='structural'` to SequenceWidget

According to the docstring on Widget:
> However, if the default
> mapping widget encounters a child widget with the category of
> ``structural`` during rendering (the default mapping and
> sequence widgets are in this category), it omits the title.

The default for a SequenceWidget should be "structural", but
it's missing.

This deals with issue #232
