All config variables starts with low-case and uses camelCase.
If there is abbreviation at the beginning of the name, the whole
abbreviation will be written in low-case.
If there is abbreviation at the end of the name, the
whole abbreviation will be written in upper-case.
For example, rssURI.
Enclose `{{ .Content }}` with a `{{ if .IsPage }}` test to avoid
the "Content is not a field of struct type *hugolib.Node" error.
Thanks to @spf13 for the tip! Fixes#366.
Also update example to Hugo v0.12 conventions:
- Convert config.yaml to config.toml to follow what
`hugo new site /path/to/site` generates
- Rename layouts/chrome to layouts/partials
- Convert `template` calls to `partial` calls
- Add .gitignore to ignore the `public` directory
- Add README.md with pointers to discussions in issues
to help bring newcomers up to speed with this multilingual example
