"This candelabrum has no candles. To attach candles, apply them instead
of the candelabrum."

It wasn't obvious enough before that the Candelabrum has seven candle
slots. This makes it show it clearly.

Minor change to reduce some annoyance when monsters quaff polymorph or
trigger polymorph traps and the player can see it: traps have no
messages at all, so the player needs to notice that a monster
polymorphed and may need to farlook it to see what it is (for instance,
if it becomes a brown H); whereas potions just say "foo suddenly
mutates!" which is nice for letting the player know it happened, but has
the same need-to-farlook problems.

This commit simply enables newcham()'s message printing for when a
monster steps on a polymorph trap or drinks a potion (the "suddenly
mutates" message is removed.)

Such a scroll doesn't practically remove the curse from anything, so
this message is misleading. It still prints the unique message "The
scroll disintegrates."

It's useful to get a message as indication you suddenly moved somewhere.
For instance, MSGTYPE=stop can be used on this to avoid bumbling in the
wrong direction after a spontaneous uncontrolled teleport.

For much the same reason as the horizontal teleport message: various
forms of level teleportation produce no message indication at all that
you just ended up somewhere else.

Ported from SpliceHack. Continuing in the trend with the last two
commits, it's nice to have a message that indicates something you might
not immediately notice just by looking at the map display.

Note that this does inform you of pursuit when you can't see the
monster.

The general idea here came from SpliceHack -- give each alignment a
unique effect in what happens to its sacrifices -- but the "puff of
smoke" in Splice seemed too small.

This is originally from the variant SliceHack. Rationale: there's still
fire being summoned, so it should vaporize some water.

Message is a reference to The Silver Chair. Most of the other races had
their own messages already, but gnomes would just default to discussing
dungeon exploration, which doesn't make that much sense most of the
times when you would be chatting to them in their own mines.

The quotation is edited from the source to reflect the dungeon
environment, but the sentiment is actually pretty spot-on given the
average player's win ratio.

Note: this doesn't interfere with the South Park gnome speech added to
3.6 a while ago; that only occurs when hallucinating and this only
occurs when not hallucinating.

Inspired by a Dudley's Dungeon strip. No gameplay change, just flavor.

Backported from TNNT. Only affects dumplog pline history, not any other
form of pline history.

The impetus for this is to avoid dumplogs full of "Unknown command foo."
messages which don't provide any value for people reading the file. In
many cases, these messages crowd out the actual message history, making
it hard to reconstruct what happened.

Triggers when you feel more confident in your skills. This is to address
a problem I have heard about several times from newer players: unless
you pay close attention to the guidebook, nothing in the game actually
indicates that you can level up your abilities and how to do it.

Experienced players don't need this message, of course; they can hide it
via MSGTYPE if they really hate it, but I additionally added a clause
that prevents this message from being displayed more than once per game
session. (It didn't seem important enough to make a save field for.)

Rather than just informing the player that saving and reloading might
fix the problem, they are now encouraged to report the problem to the
value of DEVTEAM_EMAIL. If the sysconf specifies SUPPORT, that is also
presented as an option.

From SliceHack. Note that this refers to the description of the physical
bottle; it's a substitute for "phial", "carafe", "flask", etc. such as
are seen when a potion crashes on someone's head. They don't obscure the
randomized appearance or actual potion identity.

The SliceHack version evidently went through several revisions; just
take the current one.

From SliceHack. Now if you are hallucinating and your god says
something, they will bray, moo, squeak, belch, etc. instead of booming
or thundering like normal.

It's confusing and served no purpose; a spoiled player knew what it is,
an unspoiled player might think it was a hook-hand or something. Now
they all show up as grappling hook.

It was sort of silly that the can of grease could rust because it was
made of iron. In real life I've usually seen grease stored in plastic
cans.

With them not being iron anymore, they didn't need to be HI_METAL (which
is an overused color for tools anyway), so the color is now bright blue,
which no other tool uses.

This feature is originally from SliceHack, but the original code
directly edited the monmove code, whereas I thought it was cleaner to
use the existing mtrapseen code. Thus, this commit just marks trapdoors
as "seen" for all non-mindless monsters generated in the Castle level
(the same way all monsters in Sokoban are marked aware of pits and
holes).

This change prevents these Castle monsters from moving onto trapdoors
97.5% of the time. (A determined player can still patiently sit and wait
for everyone in the castle to plunge like lemmings into the trapdoors,
but it will now take 40 times as long.) Also unlike SliceHack, this only
excludes mindless monsters - not all non-humanoids. There are plenty of
intelligent non-humanoid monsters generated right next to the trapdoors,
after all.

This is aimed at better flavor (the inhabitants of the castle should
know about the traps in their own area) and better scenery in the Valley
(doesn't seem as much of a valley of the dead if there are hordes of
soldiers milling around down there).

I considered sticking an in_mklev condition onto this if statement, so
that monsters spawned into the Castle after its creation will fall down
the trapdoors, but ultimately decided against it.
