[crossfire] autogeneration of news file

[Mark Wedel]

  In my mind, the news file should contain broader/bigger changes.

  Grabbing all the data from the Changelog is likely to be more data/detail than 
most people care about.  Are players really going to care that the global arrays 
are now consts, or that pointers have been fixed up?  Probably not.

  You could perhaps limit it to 50 lines of the most recent changes.

  However, I think it would still be best to just hand edit that file for 
changes that players should really be aware of.

  That way, players are actually likely to read it.  If you otherwise just get a 
list of changes that you ignore most of the time, you won't notice the few times 
there are changes you actually care about.
