[crossfire] Another bug on tracker :)

Hello.

About bug 
https://sourceforge.net/tracker/index.php?func=detail&aid=1527978&group_id=13833&atid=113833 "summon 
fog spell is somewhat broken", here's what happens:
* the fog summon code uses the same code as pets
* based on level, it'll generate some fog squares
* it tries inserting rotating around player
* when hitting a wall, it just stops trying to insert

This raises the question of what the behaviour should be, for pets and fog 
too.

Should fog appear randomly, like pets? Or always try to surround player? Or 
appear like "darkness" or "create earth wall", in a line perpendicular to 
player's direction?
