[Partial fix for ticket #114] Fixed broken trigger support in the KeyboardDevice?.

The trigger actually does need the KeyUp? event (which was removed in [333]) to detect whether the trigger is currently held.

[Henrik Heimbuerger]

Please review my modifications, as I don't quite understand everything in KeyboardDevice.

Also, is it really necessary to duplicate the ControllerSignal in poll()?

[Henrik Heimbuerger]

This currently prevents lane changes using the keyboard.

I tested Wiimote, Mouse and Keyboard all works fine for me. see next changeset
