After a month of changes to libipuz, I finally got the new editing interface working. These changes make it possible to differentiate between broken puzzles and correct-but-unhelpful puzzles, with an API to fix the latter. As a result, I extended the #GNOME #Crosswords Editor to edit barred puzzles.

Note: barred puzzles are basically impossible to set, and I'm in awe of anyone who is able to make a grid work. Maybe someone can make a cool puzzle with this.
