nautilus-file-operations: Prevent change permission on container directory
Changing permission for Enclosed Files also changes current folder (container) directory permissions.
This change anticipates the check on whether the current GFile is a
directory and if so it calls set_permissions_file
on contained items
only. If, otherwise, the GFile is not a directory, previous behavior is
maintained.
Closes #810 (closed)
