Very small fix for numberPadDecimalPoint


On a few keyboards (french mac keyboards for ex), the decimal separator key of the numpad is a comma instead of a dot. It is not detected as a numpad keypress on the current mac version. A fix is to add

'*', KeyPress::numberPadMultiply, '/', KeyPress::numberPadDivide,
'.', KeyPress::numberPadDecimalPoint, 
',', KeyPress::numberPadDecimalPoint, 
'=', KeyPress::numberPadEquals



Cool, thanks!
