Sandstorm code

[UnderSeven]

Weather direction is nice, but I think it needs to be PAINFULLY clear what weather you can see in and what weather you can't.  Think if you were new in this game and you died cause you went one room too far and didn't know the difference between a harsh storm or a fierce storm even when doing weather <dir>.  Frankly if it were reality you wouldn't have to try to figure out what wording god meant for what you could see with your own eyes if you were trying to determine what weather was marginally traversable in and what wasn't. 

I think the weather description needs to basically spell it outand call it blinding in the weather command if it's blinding and not if it isn't.
