Weather - More permissive wind info indicator + auto-enabling when throwing grenades

[mrschick]

When merged this pull request will:

• Make Wind Info indication more permissible, by preventing it from being disabled when looking at the map, carrying, dragging or entering a vehicle (useful for mortar/turret windage correction);
• Temporarily enable Wind Info while in the Advanced Throwing interface, to aid in placing smoke grenades effectively;

It seems that Static Weapons cause the player's eyePos to not get any wind, despite being open. Meanwhile some APC passengers do get accurate wind despite being in a closed compartment.
How could that be fixed?

I guess for static weapons we could add an offset to eyePos height, should be good enough, if a bit of a hack.

Neat idea, I guess a quick (eyePos ACE_Player) vectorAdd [0, 0, 2];, should do the trick.

1m offset works like a charm on turrets, including RHS USAF+AFRF ones.
