Fabio Alessandrelli 9100db7b94 Keyboard Input modifiers do not block actions. 
This means, if you press "F" while holding "shift" and there is and
action registered for "F" that action should be pressed.
This commit restore this behaviour, lost when implementing
is_action_just_pressed.
If you want "blocking modifiers" you should code it via script.
