move the itix theme to the root of the site

The theme was only used by this site. Having it at the root of the
repository removes the need for a git submodule and the double commits.

- layouts, assets, i18n and static files moved to the root
- theme LICENSE kept as LICENSE-theme
- ./hugo now generates chroma.css in assets/css
- remove the obsolete static/css/.gitignore

The generated site is identical, except for the stale /css/chroma.css
and /css/.gitignore files that are no longer published.

Closes #12

-## How to update the theme
+## Theme
 
-You can update a theme to the latest version by executing the following command in the root directory of your project:
+The theme lives directly in this repository (`layouts`, `assets`, `i18n` and
+`static` directories). It was previously maintained as a git submodule in
+[hugo-theme-itix](https://github.com/nmasse-itix/hugo-theme-itix), whose
+history has been merged in this repository.
 
-```
+It is derived from [hugo-theme-diary](https://github.com/amazingrise/hugo-theme-diary)
-git submodule update --rebase --remote
+and released under the MIT license (see [LICENSE-theme](LICENSE-theme)).
-```
 
 ## How to change the Chroma style for syntax highlighting
 
-```sh
+The Chroma style sheet is generated by the `./hugo` script in
-mkdir -p static/css
+`assets/css/chroma.css`. To change the style, edit the `--style` argument
-hugo gen chromastyles --style=perldoc > static/css/chroma.css
+of the `hugo gen chromastyles` command in the `./hugo` script.
-```
