Minor improvements in list box widget.

- Current time was broken because getTimeSinceEpoch() gives a time in seconds, so the timeout for double click was 500 seconds.
- I disabled the timeout for double click anyway because it's IMO not needed (and it was broken anyway and nobody complained). Second click on the same element always sends the "selected again" event.
- I removed code that hovers new item when mouse is moved during selecting because it was working rather strange. For example it was possible to slightly move a mouse during selecting the item and the action was executed on the first click, even if we expect double click.
- Action is executed on single click on Android
