fix for Issue #9

commented out // self.InitKeyboard();
and replaced by
$('.active').hasClass('hbk') ? $('.active').removeClass('hbk') : '';
in analogy to your previous fix

no clue why you need the check first, could just write active addclass
and active removeclass i guess... up 2 you to cleanup if theres no good
reason to do that as i suspect

also corrected legend hbk border style
