Reworked the PulseMode in HexMapMouseInput && CardSystem.
Added HexMapRayListener to override input from HexMapInputListener,

But if a system need a more precise output it can override the result and give his own hex result, so this will be the result provided by the system who will be send to all listener. @See EntityFieldSystem for an exemple.
