app-module: - Implement `AppStartContext` to reduce amount of `app_start_` and `app_exec` functions: replace them with `app_start_with_context()` - Add support for environment variables when starting apps - Implement support for environment variables for apps graphics-module: - Add this new module - Move font-module code into this module - Implement pixel_buffer apps: - Terminal app: reduce memory usage by only buffering a single row of characters, and try to buffer in IRAM when possible. Implement new pixel_buffer. - App List: Mark apps as favourite to pin them on top. Use touch or press "x" key. - App List: Add toolbar button that shows alert dialog with info about using favourites
