Any unhandled packets within pages are now loaded and saved intact albeit with no way to edit them. File handling is now two separate processes: parsing TTI files into packets, and then interpreting the packets into how pages are displayed. This will allow us to import other file formats, and to deal with page functions other than Level 1 Teletext pages.
