Integrated selection of bailout in the diluent selection page: To be able to introduce a new menu page for future development, the selection of bailout cases is now combined with the selection of the diluent at one page. To enable this the concept of a "shadow page" has been introduced. With that the original functionality may be reused without need to a a standalone page. The bailout /diluen page is now switched (surface mode) using the last menu line of the gas selection page
