first steps to remove the shared folder:

- mount shares to the root folder instead of "Shared/"
- navigate in shared folder and sub-folders
- show previews
- show correct file permissions
- download/edit files
make sure that we have the right permissions for the mount points
no exception for the root of the mount point (formerly Shared/), just get the file cache information from the cache
user should be able to rename/delete shared files if the owner allowed it
