Migrating to a new website engine

After almost two decades, the dCache.org web content has been migrated from regular HTML pages written by hand to a modern static site generator based on hugo with the Mainroad template.

This change will simplify the maintenance of the web pages and will allow developers to keep the content up-to-date. New pages and documentation can be added by simply dropping a file written in markdown format into the desired directory. The source code of the pages is available on GitHub and can be directly edited in a browser.

The new pages are following the responsive design concept, which makes them mobile device friendly.
