TODO:

* Fix Categories (2.0.?)

* Load prefs in DB modules (2.1.?)

* Import/Export prefs in Converter modules (2.?.?)

* VersionDelegator to handle different versions for Prefs and Records
  (e.g. Given version "30", it would delegate to Prefs v0.30 and
  Records v0.23).  This will be necessary the next time the prefs
  format changes but the Record format stays the same.

* require p5-palm 1.2.4
