Checking in the underlying prefs structure, and a prefPane, also fir structural integrity.  Also including a couple categories to extend a couple Cocoa objects, and some project changes to support building with the bundled prefPanes.  Also, added a contrib directory to house user contributed artifacts.  To come soon: more prefPanes, and the colorized icon store, with pref-generated notifications to be picked up by toolbars.
