Add clouds and rain

[David198502]

well, sorry for such a rude post...but i was extremely disappointed when my squadmates and me became aware of this issue, which in my view is a major bug...
somebody in a dogfight trying to escape in a cloud, is not safe at all, because for his pursuer, the cloud is not necessarlily visible.and therefore, until this issue is solved, i think clouds are a nogo for any server...and besides, especially on atag, those clouds seem to cause lag problems as well....

dont get me wrong, i would love to have working weather features....in fact i cant wait, to fly in blind flying conditions trying to find the homebase, and approach with the lorenz beacon system one day......good how i loved that in 1946...

but for now nothing is working correctly, and it has huge performance impact...
