* Add an option to *always* flash on chapter boundaries
* Optionally, in flash on chapter boundaries mode, also flash on the *second* page of a chapter.
(There's often a large river at the top of the page on a chapter's first page)
* In CRe, request a flashing update when there is significant image content on the page.
* Register all refresh rate related options in Dispatcher, making them available in Gestures & Profiles.
