Add optional page description to the search result list. The feature can be enabled by `geekdocSearchShowDescription=true` and is disabled by default. The max length of the description is set to `55` and will be truncated automatically if the limit is exceeded.
BREAKING CHANGE: With support of the multilingual mode, we broke the `edit page` links, as the content directory was statically hard-coded into the `GeekdocEditPath` parameter. To get the correct content directory, regardless of the language or a disabled multilingual mode, we now use Hugo's built-in `.Site.Params.contentDir` parameter. Therefor, you have to remove the hard-coded `/content` part from the `geekdocEditPath` parameter in the configuration of your project.
BREAKING CHANGE: Layout file renamed ´layouts/partials/page-footer.html → layouts/partials/menu-nextprev.html`. If you use overrides, you might need to change the filenames as well.
