[keys] key events are processed twice on windows #150

On windows, open the Chrome console and hit CTRL-C (or another magic sprotty key binding): The respective actions are dispatched twice.

Reason is we get both key-up and key-down events and call the same method in KeyListener. On MacOS we get the key-up event only for the modifier key.

I changed it to use keyDown only.
