[Light Window] Close button should be connected to button release event

[Erasmo Marín]

The problem is this:

Now, the close button in LightWindow is connected to the "clicked" or the "button press" event, but I think that a better solution is to connect it to the button release event.

Why?

Because if you have a widget behind the close button that is connected with the button release event, when you close the LightWindow, the widget behind it will receive the signal too.

See the attached video.
