UPDATE4
-------------
NOTICE:  The changes which were made in the code make all save and bones 
files absolete.  Once Patch 4 is applied, all the old save and bones files
must be thrown out.


Here is a list of the main changes:

Object and monster types got a new field specifying their color, so things 
can now appear in "living color" instead having one color for all monsters,
one for all weapons, and so on.

References to monsters and objects on the floor were moved to new structures,
which support the better color handling as well as provide yet faster access.

David Gentzel provided a port for VMS.  Although extensively tested by
David and others, and found to be sound, it probably needs further
refinements.  We are appealing to those of you who know VMS (none of us
does..) to join David in his efforts to refine the VMS code.

Much of the *main.c code was moved to a new file, to avoid having to update
that common code in three different *main.c files.

VARARG handling was ifdef'd to satisfy ANSI compilers.

Almost all grey creatures now join the other gray creatures.

Monsters will no longer be created in the same room as the player, and should
no longer want to end up in the SE corner of the dungeon.

Lycanthropy is now considered a "major problem" (allowing for appeal to the
gods through prayer), some artifacts are associated with particular character
classes, various oddities involving statues, digging, iron balls, and 
throwing have been removed, and many other bugs, both major and minor, were
fixed.
