Add files from 2020/endoh2 password-protected zip

Browse Source 
The password was no longer known as the link that had a list of
passwords as provided by Yusuke in 2020 was no longer there, being
instead from 2021. I didn't have to use the Internet Wayback Machine as
I had already extracted them in the 2020 preview back then. The
spoiler/spoiler.md has been format fixed.

The spoiler.zip file has been deleted. The README.md file has been fixed
to refer to the directory, not the zip file, and a missing '`' was added
to the file that prevented proper rendering of the html.

# Opening crawl ROT13 decoder
The program contains dedicated font data for all uppercase alphabet letters.
The source code of the font is [glyphs.txt](glyphs.txt), which is a sequence of
chunks that is a ASCII code (65-90) followed by points data: `x,y,ctrl`.
If `ctrl` is 1, the point is used as control point for quadratic bezier curve.
[code.c](code.c) is the main logic for the program, which has some placeholders
for font data and something.
It decompresses the font data and renders a given text by projection. It
exploits `C99`'s `double complex` type to represent 2D points, but carefully
coded so that it does not require any `math.h` functions; you don't have to pass
`-lm` to `cc`.
[tmpl.txt](tmpl.txt) is a template for the program. [gen.rb](gen.rb) composes
the all items and generates [prog.c](prog.c).
