Don't crash when generating corpses of certain monsters

Ugly things or other corpse-leaving monsters with species type that
has COLOUR_UNDEF would cause this. There's a hack in place to prevent
crashes with &oX in wizmode, which can be removed when the relevant
code is cleaned up.
Simplify.
Fix monster::is_actual_spellcaster()

Alternately: De-Simplify.
Alternately: Copy+Paste Considered Harmful.
Alternately: wheaaaaaaalllllsss
give an indication about where we are at in the test suite
stop crashing when trying to place lost monsters in abyss
Slightly tweak ^ screen text display

Align god title and favour better and more tightly, move the blank line
separating the two before to before the section.
Remove the additional centered "Religion" heading that was a bit
distracting, display it in the upper left corner instead if applicable.
Overall, cycling through the three modes on ^ should feel more smooth now.
Make mpr() take a string.

So that c_str() isn't necessary; const char* are automatically cast
up, so the interface for using it should remain the same.
Eradicate an ugly paradigm.
Replace 'mprf("%s", x.c_str())' with 'mpr(x)'.
Update compiler version list.

Maybe older clang works; update this is that is the case.
Remove Okawaru corpse sacrifices
Standardize Okawaru piety clock

Since Okawaru piety needs to be adjusted anyway, there's no reason not
to make this a bit more consistent.
Adjust Okawaru piety to account for no corpse sacrifices

The new number is mostly an estimate, but it can easily be changed
again.
Adjust potion prices for item destruction destruction

Most 'tactical' potions are up by 50-60%, since they're less
likely to be destroyed, scarcer in random generation, etc.
Decay and degeneration no longer cost more than other negative
potions, since Evaporate is gone.
give serpent of hell dis a reaching attack

this should make it a bit more dangerous (it seems to be the weakest of
the four by a good amount), and also fairly distinctive from the others
also tweak serpent of hell hp

coc and geh variants are a bit on the strong side - i don't think that
the serpent of hell is overall too dangerous, but i'd like to balance
out the level of danger between the branches a little better
Remove plojy (place_shop_spec)

RIP, a piece of crawl's history.
