This mostly change player to be by reference instead of by index.
But additionally it does stript checks for gold in the belt, move some
value types to the initialization and short circute a few functiongs.
`std::make_unique<T[]>(size)` always zero-initalizes the array.
C++20 has `std::make_unique_for_overwrite` to avoid that, while
older C++ versions can use the approach applied here.

Temporary commit
In multiplayer, the hash and block tables are kept around between the
saves (presumably to improve performance).
When leaving the game, they should be cleared.
Clearing of the tables is handled by `Archive::Close` in `mpqapi.cpp`.
After 135f5e03c7,
which moved the archive closing inside `pfile_write_hero`, the tables
were no longer cleared on `pfile_flush_W` (because the archive was
already closed when it was called).
To fix the issue, this commit adds a `clear_tables` argument
to `pfile_write_hero` and removes the `pfile_flush_W` method.
