Process a key press. Any key press (not release) while the
focus is in the board comes here. The key code is event.key()
and the names of keys are defined in the Qt namespace, see
http://doc.qt.io/qt-5/qt.html#Key-enum
If we can handle the event we do; else pass it to our parent.
Note that in left, right and rotate keys, we could look at the return
from tryMove() and if it is False, we could maybe implement the "wall
kick" feature.
