use include 1337.mk to hold 1337 hacker rulz

Updated 1337 hacker rulz to version 7.

Added `1337.mk` to contain the updated 1337 hacker rulz (v7).

We use an optional include of `1337.mk` (or `../1337.mk`,
or `../../1337.mk`) to include the 1337 hacker rulz.

Changed `make deep_magic` to `make more_magic`.

Changed `bin/tar-entry.sh` VERSION from "1.3.7 2024-07-22"
to "1.3.8 2024-07-23".

Changed `bin/tar-year.sh` VERSION from "1.2.5 2024-07-22"
to "1.2.6 2024-07-23".

Add `make new_entry` to `YYYY/Makefile` and `template/Makefile.year`.

Change `make new_year` to use `sort -n -u`.

Made minor debug message fixes to `bin/new-year.sh`.

Changed `bin/new-year.sh` VERSION from "1.3 2024-07-23"
to "1.3.1 2024-07-23".

Improved `bin/add-dir.sh` to update `YYYY/Makefile` with
the new entry directory name.

Changed `bin/add-dir.sh` VERSION from "1.0 2024-07-21"
to "1.1 2024-07-23".

Performed `make www` to accomplish the above and to test under macOS.
