Add SwipeDelegate::swipe.open()

This allows nice tricks, such as opening the swipe on click to expose
more details for clicked delegates.

[ChangeLog][Controls][SwipeDelegate] Added swipe.open(side) method that
can be used to programmatically open the side item on the specified
side, which can be either SwipeDelegate.Left or SwipeDelegate.Right.
