* Add logo and title customization to the masthead
* Adjust config description
* Add test site logo to `/test`
* Document `site.logo` and `site.masthead_title`
* Update CHANGELOG and history
Current we hardcoded the `pathname` for `issue-term` when we are using utterances comment provider.
It would be better for let users customize it by setting a `site.comments.utterances.issue_term` in their `_config.yml`.
* Accessibility: Add aria-label to the search button
* Update button aria text
* Add aria text to menu toggle
* Add span for search toggle
* Update span for menu label & remove aria
* Update ui-text.yml to add search_label
* add integrity hash for Font Awesome script
As the script is loaded from an external CDN (use.fontawesome.com), its integrity must be ensured mainly for security reasons.
This hash must be updated together with the exact version of Font Awesome, as given on their website.
* Update to FontAwesome 5.5.0
* Add jekyll-include-cache plugin
* Cache "static" includes to improve build performance
* Update CHANGELOG and history
"Static" refers to those includes that don't rely on data passed from the page content.
Deprecate hardcoded footer links in favor or new `footer.links` array for any link and in any order. All of Font Awesome's icons are available for use.
```
footer:
links:
- label: "Twitter"
icon: "fab fa-fw fa-twitter-square"
url: "https://twitter.com/username"
- label: "GitHub"
icon: "fab fa-fw fa-github"
url: "https://github.com/username"
- label: "Instagram"
icon: "fab fa-fw fa-instagram"
url: "https://instagram.com/username"
```
Deprecate social networking links in `_config.yml` in favor or new `author.links` array for any link and in any order. All of Font Awesome's icons are available for use.
```
author:
links:
- label: "Your Website"
icon: "fas fa-fw fa-link"
url: "https://your-site.com"

url: "https://github.com/username"
- label: "Instagram"
icon: "fab fa-fw fa-instagram"
url: "https://instagram.com/username"
```
Fixes#1581
Implement feature #1652 google custom search support. For now we only support the look and feel "results only" and the engine must be set to use that layout. Add a google section to the search providers and search_form and search layout.
Close#1652
