Show weight of unambiguous objects, hide for floor containers

The weight of all objects is now shown, except where it would leak
information the player shouldn't have, e.g. loadstones, container/statue
contents.  In particular, things like polearms that have a name and an
undiscovered description that always match like polearms and scimitars
now show their weight.
Confused throne #loot takes time, may vanish throne

Confused looting with gold now takes a turn, and if this is done on a
throne to summon a monster, the throne has a 1 in 50 chance to vanish in
a puff of logic; thrones should not be a source of infinite experience
and objects.
NH4: Wrap query text for ynq prompts

Extracted from the following NetHack4 commit:

Always put a border around prompts.

Wrap query text for text input prompts

This also limits the line input window width to 80 columns to avoid
having to do weird reflow logic if the terminal is resized mid-prompt.
Int 18 or blessed crystal ball prevents explosion

This should open up more opportunities to use crystal balls without it
backfiring and losing it.
Water damage may disintegrate scrolls

50% chance for scrolls to disintegrate instead of just being turned into
blank scrolls.  Players shouldn't be rewarded for hauling a ton of
scrolls to a fixed water source.

Scrolls can still be blanked with cancellation.  Some scrolls might even
be used for their intended purpose instead of as blanking fodder.
Stop wraiths following across levels

Luring wraiths off graveyard levels for a higher chance of dropping a
corpse is slow and boring, so don't reward players for doing it.
Color nymph garden rooms bright green

Idea from UnNetHackPlus by Bulwersator.

There are some really strange bugs in the vision system if the
front-end's recoloring doesn't handle darkroom_id spaces; the whole
vision system is a giant mess.
Trees, fountains and message for Nymph level

"You hear sounds of nature all around you."

This should give players more warning when they stumble onto this level,
so they can decide if they want to explore it or just skip it for later.
It also makes it look more interesting.
Show "(very) rotten" on old corpses

If a corpse has a chance to cause food sickness it will show "rotten" in
its name.  If it's guaranteed to cause food sickness it will show "very
rotten" in its name.

This addresses the most common cause of death for new players (food
sickness), without holding their hand.
Shorten floating eye paralysis, wisdom limits duration

Floating eyes taking a well-equipped full health character to instant
death was absurd, so make it less likely and easier for certain
characters to mitigate.

The passive paralysis of floating eyes is now (HD+1)d35 instead of
(HD+1)d70, where hit dice is 2 but can vary depending on when they're
encountered.

Passive paralysis no longer has a 1 in 4 chance of being maxed out to
127 turns instead of its intended duration.  Instead of wisdom
preventing this, it now sets the maximum turns to 10 * (20 - wisdom),
down to a minimum of 10 turns.
