Implementated corner passthrough when touch exploration
controller is on.
If the user presses and holds the bottom right or left
corner of the screen past a time delay, an earcon will
sound, and then any subsequent fingers added onto the
screen will send touch events as normal (passed through)
as long as one finger is at a corner of the screen. Once
the finger on the corner of the screen has lifted, then
nothing will happen until all the fingers on the screen
have been lifted.
UPDATE: Added earcons (short sound notifications) to
indicate to the user if they have moved their finger off
the screen or onto the screen or if they are in passthrough.
BUG=396310
