*
* VERSION 4 added a bibtex-field name for Bibtex collections, element name was
* changed to 'entry', field elements changed to 'field', and boolean fields are now "true"
*
* VERSION 5 moved the bibtex-field and any other extended field property to property elements

*
* VERSION 6 added id, i18n attributes, and year, month, day elements in date fields with a calendar name

*
* VERSION 7 changed the application name to Tellico, renamed unitTitle to entryTitle, and made the id permanent.

* VERSION 8 added loans and saved filters.
*
* VERSION 9 changed music collections to always have three columns by default, with title/artist/length and
* added file catalog collection.
*
