Fix Input::getKeyCode on software keyboard layouts 
Input::getAscii goes Torque keyCode -> SDL Scancode -> SDL Keycode -> SDL ascii key name
Input::getKeycode used to be SDL ascii key name -> SDL Scancode -> Torque keyCode

This mismatch made software keyboard layouts behave incorrectly in different places. For example, you would bind a key to an ActionMap and it would activate with a different button than specified.
