fs-browser was originally developed by apchelintcev - we use it on the micro tutorial Content app with non-JCR content

At least since Magnolia 5.6 it is not working anymore - due to the upgrade to Vaadin8.
We (doc guys) should update it.

GIT: https://git.magnolia-cms.com/projects/DOCUMENTATION/repos/fs-browser-app

See comment from fadiwissa at Content app with non-JCR content

I need to create a custom content app that simply lists items from a REST endpoint (with the ultimate goal of allowing users to select from such items to use in another app)
I was hoping to start from the fs-browser-app but this does not work on MGNL 5.6 (due to a vaadin error)
