Subject: Fix Mappings in PictureViewer2

Another fix for the new MappingTreeModel database layout: Make the
mappings display correctly when showing an archived picture.

For performance reasons I had to make PicFilesModel global and put it
into a separate file.

Also clean up MappingTreeModel: remove comments and unused functions.
