Swap over a position of cursor while reaching the end of filename in keyboard

In sansa clip + with virtual keyboard you can write/rename a stuff and move
your cursor in the filename field. But while your cursor reaches the end/start
of filename it just blocks the movement of cursor and beeps if you enabled the
"Voice Menu" feature. This patch swaps over cursor to the start/end of filename
instead of just blocking movement.
