ContentList content type; getting content items/lists from Options generically via content.Items, and a new addContent widget function. Several improvements to generic handling of content. New button-with-text widget.
Some tidy-up.
Some name changes, to increase uniformity.
Bug-fix: floating widgets of fixed size could previously be made larger than intended from config dimdata.
