The "done" and "fail" callbacks both update the item for the uploaded
file using "setFileIcon". "setFileIcon" updates the contents of the
"<li>" element for the file, but the "fail" callback was giving
"setFileIcon" an element generated by the template, so the resulting
HTML contained a "<li>" element nested in another "<li>" element.
However, generating the HTML is better done through a template, so the
template now receives the icon to show in order to be used by a
successful upload and a failed one, and "setFileIcon" was changed to
"updateFileItem".
Note that the mimeTypeUrl does no longer need to be escaped, as
Handlebars templates escape the needed characters automatically.
