Arvados » Arvados Workbench 2

When clicking the "Download" item on the "more options" menu of a file it redirects the browser to a keep-web URL like:

https://download.cluster_uuid.arvadosapi.com/c=cluster_uuid-4zz18-something/some_image_file.png

...resulting in keep-web/browser to show an authentication dialog.

WB2 could pass the user's token to avoid this:

https://download.cluster_uuid.arvadosapi.com/c=cluster_uuid-4zz18-something/t=users-token/some_image_file.png

I also have issues with the file preview, it just shows an empty box with a question mark. I think this may be the same issue.
