The way the size and weight of corpses was calculated was just ridiculous. A
dwarf running around with the corpse of, say, Tiamat slung around his back?
Give me a break. Now the size (and hence, weight) of the monster that met its'
demise actually affects the size and weight of the corpse.
Additionally, preserve corpse was altered so that it helps you a bit with the
increased weight.

PS. Them nasty dwarves can probably still run around with Tiamat corpses,
gnngnnn, nasty strong critters with them beards...
