Sniper Rifle fix.

You have no HUD when zoomed.  None, I'm unable to move every HUD element while zoomed in so you lose it.  Consider it part of your concentration while zoomed in.

If you move while zoomed in you automatically zoom out, you lose concentration.

If the rifle isn't in your active hand you can't zoom in.
