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.
