* Darken the inaccessible areas of the scene. (This is a quick-and-dirty solution; the clean solution would be to enlarge the scene rect when puzzle 
pieces are moved outside the scene rect.)
* Prevent the make-puzzles.sh script from trying to build a puzzle from default-collection.conf.
* Increase the minimum plug length in the jigsaw slicer. (Some people complained about too small plugs.)
* Fix part movement constraining: The shadows should not be taken into account when calculating the bounding rect of the piece.
* Fix a crash in the Scene that occurs if the game is restarted after the current puzzle has been deleted from the library.
* Enable the user to load a puzzle by simply clicking (or double-clicking, whatever he has configured globally) the item in the library view.
Also, add a TODOLIST with notes I've taken at a testing session last week.
