vibrate property
A vibration pattern to run with the display of the notification.
A vibration pattern can be an array with as few as one member. The values
are times in milliseconds where the even indices (0, 2, 4, etc.) indicate
how long to vibrate and the odd indices indicate how long to pause. For
example 300, 100, 400 would vibrate 300ms, pause 100ms, then vibrate 400ms.
