Make it possible to pass rawlist.php an JSON array, to filter by more than one mimetype
Only use mimetype_list and clean up a bit
Sort files by name, not by mimetype
Use usort() instead of uasort() to not maintain keys
Use shorter array-conversion
Split some lines, use ===, avoid unnecessary operation
Clean up rawlist.php and fix non-array request
Merge pull request #4735 from owncloud/multiple_mimetypes_rawlist
