build compressed tarballs for all of the IOCCC

Folded `all/README.md` into top level `README.md`.
Removed `all/summary.txt`.
Moved from `all/all.tar.bz2` to `ioccc.tar.bz2`.
Removed the `all/` directory.

Added `bin/tar-all.sh` form a compressed tarball for an IOCCC year:

```sh
bin/tar-all.sh -v 1 -W
```

Improved `bin/gen-years.sh`.

Added `make form_all_tarball` to `make quick_www` and `make www` in the top level Makefile.

Performed `make www` given the above.  Some entry compressed tarballs
were updated due to recent updates.
