Don't crash when trying to save corpses
More item.rnd fixes

Initialize it in the places that used to set colour manually, and
add yet another tag.

Also, let unrands go without rnd, since they don't need it.

This should be the last...
Don't crash when looking at \ (johnstein)
Don't generate +144 rings
Remove some dead code.
Unionise monster::number.

While possibly most of these should be converted to props, number _is_
more efficient. This should also make it easier to change them to props
if that does seem like a better idea.
Unionise monster_info_base::number.
Fix compilation (gammafunk)
Sync manual from wiki (monster xv)
Don't crash when generating unrands
Misc item code cleanup
Spider walls brightened, minute tweaks to lab walls and lair floors.
Don't crash on ?/mhydra
Unbrace
Incredibly, unbrace again
Fix an assert.
Don't crash on xv of monsters remembered past saves.
Move the sacrifice_def definition to sacrifice-data.h (PleasingFungus).
White marble floors for Tukima wizlab, removed rim from Flayed Ghost.
Don't clone monster death keys (#9120).

So that phantom TRJ does not open the Slime vaults on disappearance.
