Rename UI_UPDATE as MOVE_UI_UPDATE
All the other constants named UI_* are special key names that can be passed to midend_process_key(), but UI_UPDATE is a special return value from the back-end interpret_move() function instead. This renaming makes the distinction clear and provides a naming convention for future special return values from interpret_move().
