This makes the exmaple a bit more realistic, because you wouldn't
usually want to serve the directory the .nix files are located in.

It also demonstrates how to point to a directory. Beginners might
struggle with trailing slashes and other details of specifying a path.

Finally it makes the example work as-is.

Fixing some structure problems in the slides.  What's left to do is to
make sure the modules chapters and advanced chapters are better
structured and possibly add some more examples for modules as well.

This deck might need to be renamed, because it's not _only_ advanced
concepts but also common patters, etc.  Also TODO: replace all my
hand-drawings with nicer SVG diagrams in the future

The start was re-structured to have a bigger focus on the fundamentals
of how the module system is implemented in the runtime, and then
provides more usage examples before going into how to write custom
modules.
This deck now also features submodules, and special types such as
listOf and attrsOf.
