desktop part is done, not so much icons are actually used locally, so I've updated only those in resources, rest is fetched from the server (activities)

As discussed with @marcoambrosini in Talk, this is what needs to be done:

• Create SVGs for the folder icons which have combined folder icon + state icon (like for sharing, external etc.)
• Collect the other filetype icons as they are now loaded via MDI and not from core/img/filetypes anymore – Some are listed by @nimishavijay for the "New" menu issue already in Better arrangement of items in "New" menu in Files server#43728
