Add a delay between the second button down-up event of double taps
Some applications ignore the second tap of double taps because of the
lack of a delay between the button down and button up events.
Prevent this by replacing the transition from TS_2B to TS_START with a
transition from TS_2B to TS_SINGLETAP that emits only a button down
event. The button up event will be emitted when transitioning from
TS_SINGLETAP to TS_START.
In addition, decrease the default value of MaxDoubleTapTime from 180 ms
to 100 ms in order to make double taps faster.
