Add "Unhide hand (only when activated )" option

It would be more realistic if player's hand is out of the screen until its actioned, no one walks with his hand in front of him for as long as he lives or withouth never seeing its own hand, there should be an option besides; Hide hand (on/off) , a point in between the two options offered at the moment, an option for players who would like to see the world while roaming around and also see the tools (only) when being used, it would fit perfectly with third person view.

Also, the shield it's always vertical, even when it's not in use wich has no sense (in comparison with the third person) view.
