FotoToon should have nice friendly help hint for new activity instances

[garycmartin]

FotoToon (testing with v13) should have nice friendly help hint for new activity instances. Currently the fist experience is mostly an uninviting grey screen. It could start with a suggestion, something like 'Add an image and start creating your FotoToon', with a large Add Image icon above the text, and a button below the text to 'Add image'. This would get the user oriented to know what the main functionality is. The blank canvas hint layout would be similar to the recent design work done for canvas hints as seen in Jukebox (when empty), the Journal (when no query matches), Home List View (when no query matches), etc.
