Nice! Add just changelog pls

Would be good to have tests that check that the name of a unnamed link is really something that looks like the token. Something like

When user "user1" has created a public link with following settings
    | path        | simple-folder         |
Then a public link with the token as name should be listed for resource "simple-folder" on the webUI

please ping me if you need help with it
