Base panlord tile recolouring (roctavian).

To give them a colour that can be recoloured in dc-* tile directives.
Inherit panlord colours in tiles from console colour.

The exact colour adjustments should be cleaned up, but the basic
implementation is here.
Show elemental colours for panlords too.

Since we do get the occasional ETC_RANDOM...
Modify pandlord color schemes
Panlord body & head edits
Line up panlord descriptions with tiles.

We're losing a lot of descriptions in the process here, but there's a
hunger to make new panlord tiles anyway, so we can bring those back once
we have tiles for them.
Remove a stray debugging include.

GGGRRRUUUNNNTTT
Fix compilation (doh)
Panlord wing edits
Panlord description fixes/changes
Scattered minor monster tweaks.

 * Remove poisonous bites from two spiders that already have distinct
   non-poisonous offense, jumping and orb. The former gets a slight
   damage boost to the bite to compensate (not that the poison was
   previously seen very often anyway, since 5 damage won't get to
   trigger poison against nearly any ac), the latter gets nothing since
   it takes discord or frenzy to even see them bite.
 * Give Mnoleg more exciting attack verbs, since he is juxtaposed
   with klowns now and they get such exciting attack verbs themselves.
   The only influencing aspect of this is that one attack counts as
   a claw for hydras.
 * Give Dissolution 4 more HD, so his poly isn't sad (for now) and
   so that he has a better chance to actually hit extended evasion
   without needing eyeball paralysis.
 * Block Killer Klowns from polymorph / shapeshifters; they're extremely
   weird to get from such, and the top hd area for the either of those
   already got the highly-dangerous birds without needing klowns too.
changelog
Simplify (r)eading books (9274)

Now exactly the same as examining them through the inventory.

Also, weirdness fixed.
Irradiate quote (9265)
Temporarily remove randlich chain lightning

Excessively murderous.

It will return in a slightly less murderous form, in future.
Improve randlich spell tweak (fishbowltower)
Add Cigotuvi's Badtile
Warn before Irradiating pals (Davzz)
Make _potion_effect not use potion types

But, instead, miscast_potion_types. (potion_like_effects...?)

Since they're not really using the potions anyway, and we'd like
to be able to change/remove potions without having to touch miscast
code!
