404 page not built anymore?

[kcgthb]

Description

It looks like the 404 page template doesn't work anymore.

Expected behavior

Get the templated 404 page when accessing a non-existing URL.

Actual behavior

Get a simple 404: Not Found text, or a redirection to the generic GH pages 404 page.

Steps to reproduce the bug

Go to https://squidfunk.github.io/mkdocs-material/foo :)

Package versions

• Python: python --version: 3.4.5
• MkDocs: mkdocs --version: 0.17.1
• Material: pip show mkdocs-material | grep -E ^Version: 2.0.1

Project configuration

not relevant.

System information

• OS: Linux
• Browser: Chrome

[max-ci]

In order to have custom 404 page on GitHub Pages you have to:

create a HTML file named 404.html or create a new Markdown file named 404.md at the root level of your GitHub Pages repository.

Source

There is no such file in gh-pages branch in this repository.

There's in fact a config option that was forgotten to be included in the mkdocs.yml of Material. 404 pages work for all projects using the theme, e.g.:
http://facelessuser.github.io/BracketHighlighter/foo (uses 2.0.4)

I will provide a fix, so it will also work in the official docs.
