This makes use of wide curses functions instead of 8bit functions. This allows to type e.g. accented letters. Unfortunately, key codes are then returned with values that could be confused with wide characters by ncurses, so we need to add a maybe_keycode variable to know whether the returned value is a key code or a character (wide support), or possibly both (non-wide support). The translation tables thus also need to be separated into key code translation and character translation. The curses2foo helper makes it easier to use them.
