Plan for layouts

[DarthGandalf]

• [ ] start with some base framework code, which will be unused for now
• [ ] then add support for .sprite files (should be easy to port from old C++ code)
• [ ] then fallback fs setup
• [ ] then redo main menu on json
• [ ] then reimplement translation
• [ ] then add other panels like the quest/inventory I shown off earlier, because texts on all of them needs to be translateable (most of texts are on char creation screen and char stats panel though)
