The W3C feed validator fails to validate RSS 2.0 and Atom 1.0 feed
elements that do not contain a valid author. This change adds an
`authors: Vec<String>` to pages, as well as an `author: Option<String>`
to Config that will act as a default to use in RSS and Atom templates if
no page-level authors are specified.
* search: Add support for a JSON index
* docs: Document JSON index for search
* docs: Use lazy-loaded JSON index
* Add elasticlunr prefix to search engine format configuration
This will be useful if support for more search libraries are added in the future
* add external_level and internal_level
* remove unnecessary debug derive on LinkDef
* clarify doc comment about link check levels
* simplify link checker logging
* add missing warn prefix
* simplify link level logging, remove "Level" from linklevel variants
* remove link level config from test site
* switch back to using bail! from get_link_domain
* move console's deps to libs
* remove unnecessary reference
* calling console::error/warn directly
* emit one error, or one warning, per link checker run
* various link checker level changes
* add docs about link checker levels
* remove accidentally committed test site
* remove completed TODO
* Make sure that zola serve/build can start from anywhere inside dir tree
* make clippy and rustfmt a bit happier
* replace unecessary if-else with unwrap_or and display which path could not get canonicalized if it fails at startup
* canonicalize config_path to avoid crash when config.toml changes
* Treat _index.LANG.md as section, not page (close#1694)
Display more advanced information in case of a future crash here
* Add link to translated local section in test_site_i18n to catch #1694
It appears linking to another translated page does not trigger the bug,
but linking to a section within the same (translated) page does.
* Allow (and test for) homepage internal links in broken link detection
