create.c: fixed @link command to take names of objects for matching,
so names of things can be used rather than strictly the numbers.
syntax (NOTE semicolons) @link exit = thing1; thing2; thing3.

db.c: conversion from old mud databases works correctly.  Sex
properties only set on player objects.  carried exits are handled
correctly.  fixed nasty bug that didn't initialize drop/odrop fields
to NULL on older-database reads.  new dump format eliminates wasteful
"*** property list begin ***" strings.

game.c: added COREDUMP option for corefiles on server panics.

interface.c: added hostnames/ip addresses in WHO list, @boot.

match.c: added match_home().

move.c: drop/odrop on rooms now run when things are dropped in them.
odrop prepends the name of the object, substituting its pronouns.

rob.c: fixed kill.  pronoun substitution works on odrops now.

sanity.c: redid it to check recursive contents/location/exits,
strange type things in exit lists, and to recognize garbage.

set.c: fixed do_name's bug with null passwords, fixed @chown;
"@chown thing = me" works as well as "@chown thing".

speech.c: enlarged buffer in do_wall(), buffer was too small to handle
a max-sized command.

stringutil.c: added prepend option to pronoun_substitute() to allow
odrops to work with kill.

wiz.c: toading now sends the victim's contents home rather than just
complaining about it.  added @boot.  added @tel thing = home.

unparse.c: CHOWN_OK objects' flags are shown to all now.

OVERALL CHANGES:  passes saber c.  compiles on a MIPS.  #ifdef'ed
property values, to save space; property values don't work correctly
without MUF.  Added player lookup hash tables, a la MUCK 2.2.
