Ben Wiederhake cfbc49b5fc LibGUI: FilePicker: Set initial sort to name instead of undefined
Well, technically the initial sort order is 'ascending inode'.
However, that is unpredictable for the user.
In the rare case it is desired, it can be re-enabled by revealing the
inode column, and then sorting by it, in the TableView.
