* GUI module submenu: fix documentation * GUI module submenu: add submenu_set_selected_item fn * App iButton: use submenu_set_selected_item to store and set selected item in submenu * App iButton: swap write and emulate in "saved key menu" scene * App iButton: file select can now switch to the previous selected file * App iButton: swap write and emulate indexes in "saved key menu" scene * Gui module file_select: work with separate extension * iButton app: separate file managment, file error handling * SD card api: custom error message * iButton app: better file error handling Co-authored-by: あく <alleteam@gmail.com>
