Fixed file sorting to work with scrolling
The FileList.files model is now updated with file operations. Adding files to the list will add to the model first, then to the DOM. If the insertion point isn't visible yet, the file won't be added to the DOM until the user scrolls down. Updated unit tests to include checking for the correct insertion point.
