[crossfire] mapcmd bye bye.

[Mark Wedel]

  Anyone have any issues for removing the original mapcmd protocol command?

  the map1/map1a commands will remain.

  Client version 1.1.0 introduced support for the Map1 command.  So I can't 
really see it breaking anything.

  Due to changes needed for the map2 command, this will require some amount of 
updating for the map1 command.  I just can't see much reason why the mapcmd is 
needed anymore, but thought I'd throw the question out there in case someone is 
aware of some issue.

  Probably the way to handle this is for the server to check after negotiation 
that at least the client has negotiated at least to the map1 command, and if 
not, print out an error and close the connection (error message along hte lines 
like your client is too old, update).

  The one issue where this could perhaps be an issue for any bots out there that 
just ignore the map data, and thus don't bother to negotiate a map version in 
the setup parameters.  So maybe this message should be considered more a heads 
up to those people with bots to make sure it is at least negotiating a map1 
protocol level?
