Functionality for attempting to treat/diagnose #7501.

Games crashing before should load now, and the ASSERT should prevent
invalid saves from being generated.
A briar patch tile.

I'm not really happy with how this turned out, but it's better than the
nothing we have right now.

Hopefully this will serve as motivation to get something better?
nicolae's "handful of vaults" (#7478).

nicolae_hardware_store was in the game already, but everything else is
in.
An old vault design of mine (by request of kilobyte).

We're all doomed now.
Fire fineffs after individual monster attacks (#6936).

This also fixes player::is_banished() for a target validity check, so if
Sonja's first attack banishes the player, the player is banished
instantly and isn't subject to Sonja's remaining attacks.

Since they appear in groups, I've restored Frenzy as their escape slot, as they'll typically have something available to maul.

Let godprayer messages and ^ description coincide with piety ranks

Using anything else than the piety breakpoints which are displayed to
players as `*` rank is just a tedious way of approximating your actual
amount of piety better. The initial difference between 5 (for prayer)
and 1 (for breakpoint) was kept because seeing a new message early on
tells players that they're doing the right things, if they are.
Add new piety_breakpoint at 160

The implementation itself is more of a hack, but coupling piety
breakpoints to god abilities doesn't make all that much sense either.
There are so many checks for piety over 160 or 161 in the code that
introducing this new one most definitely makes a lot of sense.

Of course just slapping a `+1` on top of that rather unrelated size
is just a magic number and two wrongs don't make a right. I went with
what works for me, right now, but am happy to see this code improved.

The piety_rank checks shift from 161 to 160 for consistency as well.
Change checks for piety 161 to new piety_breakpoint(5) = 160
