- check and give error message if perms could not be changed
- added sudo feature to file preferences allowing to get VFS root access
+ setup config user/password can always be used
+ further eGW users can be configured in setup >> configuration
--> allows eg. to create free folders in the vfs root
--> should be used with caution and respect to users privacy
- added file preferences icon to opened directory (eg. for the root dir)
1. filesystem (default)
2. database (problems with files > 1mb)
3. custome set via filemanager/cli.php mount
--> If you can only access the docroot, you can use 2. AND set the files
directory to the path for temp. files
