Since the WG is just another client, the server only needs to send the
usual info to it, no performance hit there.  Sending info back again would
bog down the server, if it was a large lump of info.  With the current
weather resolution, it won't be a large lump.  I am trying to cut it down
to only the info needed for the map the WG is currently on.

Exactly the opposite, the weather updates to the maps happen on maps that
players are currently on.  The current weather system also slowly goes
through the maps one at a time updating.

Part of my reason for doing the split is that I am invloved in a cluster
project, and simulating weather is a good job for a cluster.  So I want to
have the Weather God server running on a seperate computer / cluster. 
Tricky to do with threads.

Once I have the basics running, I will dramatically increase the reolution
of the weather system, but it shouldn't increase the load on the game
server.  By making the resolution a configurable parameter, ordinary server
operators won't be needing super computers to calculate weather B-).  On
the other hand, those that want more and have some spare computers lying
around...

Is any of this stuff I am doing needed?  Nope, only the previous patches I
posted are needed to make the weather system better.  Weather God just fits
in with other stuff I am doing, so I'll do it.
