NatLibFi/Skosmos: Skosmos 3.1

This release shapes up Skosmos 3 by implementing incremental loading of results on the search results page, by improving how deprecated concepts and SKOS collections are displayed and implementing support for ordered property values (credit: @jdfranel). CSS variables have been reworked to make it easier to implement color themes and customizations and a new favicon matching the Skosmos logo has been added. More aspects of Skosmos can now be controlled using environment variables (credit: @jdfranel), which eases deployment with Docker. Cypress tests have been reworked and some stale files and directories have been cleaned up in order to ease future development. The HTTP User-Agent header used by Skosmos when performing SPARQL queries and other HTTP requests now includes a version number and URL, better identifying the client application. For an overview of the next planned steps in Skosmos development, see the Roadmap.
