This builds and minifies CSS and a common JS bundle, as well as copy the relevant fonts. In order to build, we now need to run "npm run build" after installing the dependencies with "npm install".

No need to have a postload for clipboard.js in templates.
Use the class "clipboard-btn" and match the data-clipboard-target with the right ID
(or other DOM-element).

- Large screens: will display the dropdownmenu
- Medium & small screens will show a button (on the top right in the future)
and a menu will push the content (to left) and showing the language options.

- Change input type=file: style it like a label and add js function.

- Missing translations
- Converted metadata needs to be updated as well.

- Add dependencies
- Change link in script postload, base.twig
- Add function in Script.js
- Delete postload block in metadata-converter.twig and call clipboard function on button click.

add document.ready function to script.js where all the calls to selectize are made.
update base.twig. Now script.js is the last script in the list.

Change the links in the head and postload of base.twig according to the new structure and the recently added packages.
