The fs-contents-portlet and the fs-portlet (when scoped_p is true) use a
file-storage package's template to display folder contents. This template
checks for permissions and decorates the display with appropriate buttons
for adding files, folders, etc so there's no need for our portlet to add
hyperlinks. Nor to do the permission checking used to determine which ones
to put in the portlet. Unfortunately, for the unscoped case, i.e. the
user's file storage page, the portlet puts out its own page and does so
using a different style than file-storage itself. Which needs fixing, but
not right now.
