- Use 'jekyll-feed' plugin to manage RSS feed and remove existing feed.xml file
- Add feed image in main blog tab ('All posts')
The 'jekyll-feed' plugin makes possible for aggregators to automatically detect the existence of a feed (feed_meta tag in header)
and creates a 'feed.atom' file containing the last 20 blog posts and locates it in the root directory. The structure is compatible
with our current system, including the possibility to show a picture if it's included in the post (#1002).
Removed all _data/LANG/roadmap.yml files and moved all strings to _i18n/LANG.yml to take advantage of the multilingual
plugin. Also removed all loops in resources/roadmap/index.md, now we simply map to each placeholder.
This commits removes the page 'Technical specs' and adds some technical info to the 'About' page.
The 'technical specs' folder and page were removed from the repo, from the navigation menu and
the footer (for all languages)
