SUMMARY
Folderview doesn't use natural sorting

STEPS TO REPRODUCE
1. Rename >=10 files in dolphin simultaneously
2. Create a folderview of the parent dir (sort by name)

OBSERVED RESULT
Numbers are not sorted consecutively (1, 10, 2, ...)  

EXPECTED RESULT
Sorting should match dolphin exactly, which does have natural sorting
