fix orientation in image-backend, not in preview system itself
Fixed file list sorting

Now using a natural sort algorithm that is more consistent between JS
and PHP (although not perfect in some corner cases)

- added OC.Util.naturalSortComparator that uses the same algo that was
  used for the user list
- changed user list and files list to use OC.Util.naturalSortComparator
- removed toLowerCase() and changed the comparator to use
  String.localeCompare()
- added unit tests
- added OC_NaturalSort that is used by OCP\Util::naturalSortCompare()
Fixed sort algo for additional cases

Remove passing by reference to allow for proper GC

The garbage collector in PHP 5.3.10 does not properly release the file
handle when calling fclose() due to the fact that it is passed by
reference.
This has the side-effect of preventing file locks to be released as well
when the files_locking app is enabled.

This fix removes the useless passing by reference and now the file
handle and file lock are freed properly.
