Manual tweaks to supporting-files information

Again, to conform to Badgerfish. This should convert to:
```html
<params>
  <files>
    <file size="1234.5 KB" type="Comma-separated text" url="http://fakestore.blah.org/FAKEFILE.csv">FAKEFILE.csv</file>
    <file size="1.3 GB" type="Excel spreadsheet" url="http://fakestore.blah.org/ANOTHER.xls">ANOTHERFILE.xls</file>
  </files>
</params>
```
