Subject: Show mappings in PictureViewer2

Hell, this was one heck of a bitch. Lots of changes just to show the
mapping tree in PictureViewer2. Did I mention that I hate recursion?
Added a function for fetching a SmTreeItem * from MappingTreeModel for
paths, just to turn it into a QTextDocument in PictureViewer2. Of course
everything is recursive. Did I say that I hate recursion?

Well, as said in the comments, one recursion function seems fishy, but
it works (tm).
