LokiHack '99 Patch

Patch Title: Flat World and Replication
Author: Dennis Payne
E-mail: dulsi@identicalsoftware.com

Short Description:
Flat world mode along with multiplying and non healing units

Long Description:
Flat world is just a world with edges on all sides.  Multiplying creatures
do just as the name implies.  As long as they stand still they have a
chance of replicating.  The non-healing unit option is mainly intended for
limiting the replicating units.  But could be used for cheap robots or
something.  And I restored the Aztec civilization to the game since
Activision accidently left them out.

Documentation:
Flat world is an option on the new game screen.  The world currently has a
few bugs.  Path finding doesn't recognize that the edges.  Also the
exploration of certain areas is buggy.  I know where the error is
Vision::CheckWrap() but haven't corrected the issue.  Also Neighbor square
finding isn't quite right.  For units I added the slime which can replicate
but not heal.  Every turn it waits it has a 50% chance of multiplying.
(Otherwise they are identical to Warriors.  This includes the maintanance
costs.)  Finally I put in the Aztecs which should have been there all along.

Known Bugs:
Flat world still buggy.  Check MapPoint neighbor finding and
Vision::CheckWrap().  Also if war is set lower than normal the
"Can't Heal" units will start with a lower health (could add special forces
to compensate).
