Language versioning

[JoannaSendecka]

We will receive the English version of the website and will create the "language switch".
Current template does not include this functionality.

Online resources with potential solutions:

• https://leo3418.github.io/collections/multilingual-jekyll-site/add-language-switcher.html
• https://talk.jekyllrb.com/t/making-a-multilingual-website-with-collections/4824

Possible problems:

• incompatibility with the template (most probable with using the plugin)
• different folder/file structure of the template than in solution (as in several other cases)

Icon for switching languages:
It would be good to have an icon at the end of the top menu to switch between English and Swedish. Ideally it would change from one to the other dependently on the language of current page.
At this moment, all functional icons in the template seem to come from one source Font Awesome https://fontawesome.com/v4/icons/ I tried to use the custom icon instead, but it does not work, so in order to do so, we have to create another layout (maybe use current "custom"?) or change the way icons are defined (not sure where).
