Tweak session Alpha 0.309!

Another small tweak session:
-The garand now auto ejects ammo on the last shot, just like real garands!
-All ammo that is empty now looks empty when ejected
-On the start of a map the gun is properly place in the holster..sometimes it would be sideways
-added one more "hit" sound when getting hit
-tweaked the sandstorm, should improve performance
-tweaked gun fitting, all guns should feel a bit more logical in hand
-the night map now has a slight difficulty increase
-lastly..we are now on unity 5.6, in general this should bring performance improvements in the future!
