Update config.h boilerplate to use `#pragma once`

According to @fredizzimo, this is a safer and easier way to handle the
boilerplate.

Add Userspace mention

@drashna mentioned it'd be good to have a mention of the userspace in
the QMK structure section. Rather than rewrite the docs on userspace, I
chose to link to the existing documentation.

Reword the `config.h` section

This section didn't include the possibility of a user `config.h`, and it
wasn't clear exactly how the settings override works.

Update docs: `Makefile` -> `rules.mk`

I think this was a typo, or perhaps an older way to handle it.
