This commit fixes the non-intuitive behaviour, where hitting return or
space with a button focused, then tabbing to another button and
releasing the key causes the second button to trigger. It feels wrong,
as the "gesture" was never initiated on the second button. The fix makes
widget.Clickable track which key was pressed, in a variable called
pressedKey, and only considers a key release if the released key matches
the pressed key. Finally, if the widget loses focus, pressedKey is
cleared.
