FileManager: Show an inline error message for inaccessible directories

Browse source 
Instead of popping up a message box whenever we can't read an opened
directory, show the error message inside the DirectoryView (as a label)
instead.

This fixes a visual inconsistency where an inaccessible directory would
be selected in the left-side treeview while the previous directory's
contents were still showing on the right.

This also makes keyboard navigation a bit more pleasant since you're
not suddenly interrupted by a message box.
