Bug 20472: Db rev for new preference ArticleRequestsSupportedFormats

This preference controls which formats are actually offered to patrons of
the library via the Article Request feature.
By default, it only contains PHOTOCOPY. This is default behavior.

The request format SCAN will be made possible by this report and can be
added by changing the preference.

Test plan:
Run the dbrev. Check the new pref on Administration.
