 	Ahh... the original authors did this (well not the protocol, but): 
planet/primary == 0 is invalid, but they did it anyway for Mur's case it 

 	This is a consequence of the original developers (ab)using int to 
differentiate between a ship and a planet (mainly for messaging) by 
'sign'.  Also, ratfor apparently did not index arrays starting at 0, they 
used 1, and the code assumes that.  So they must have figured a 0 primary 
was impossible, and therefor irrelevant.  The protocol didn't even 
consider this. Those bastards. :)

 	So the end result is that server changes to Mur will never be 
propagated to a client.

 	Was thinking about getting away from that anyway and going with an 
'object type/id number' method of identifying objects. 'Ship 4', 'Planet 
27', or 'stargate 5' rather than the current <0 == planet, >0 == ship, 

 	Another reason to do these changes I guess.

> yes, and 0 is a valid value for primary.

 	Yes, and no.  It can be represented as a '0' in the code (now), 
but the game code itself would never have been able to access it (ratfor 
limitation I guess).  Of course we're in C now.  0 does exist! :)

 	I had considered fixing this during the original ratfor -> C port, 
but the assumption was so ingrained in all the code, I kept it.  Time to 
change it I guess.  What fun that will be! :)

 	I'll need to address this in the next major version (and what a 
major version it's looking to be (common block/protocol wise):).  That's 
why I mentioned that the New Version (NV) would hardcode a ghost0 planet 
at 0,0 on which to afix the universe.  At that point, we will have to 
allow planet == 0 as well (but it will be special - immutable).
