Change Log of GameGridKara

Update to JGameGrid version 2.23. This simplifies drag-and-drop and context-menu handling because the getActor... methods will always return the topmost actor first. This wasn't the case before and had to be handled in the GameGridKara code.
Fix some typos in handouts.
Improved error handling if world setup file could not be loaded.

Custom replacement images can be placed in a folder called "images". See new class WorldImages.
Background is now loaded from the field.png file and used as tile. This can also be changed by placing the corresponding file in the "images" folder.
Changed the naming of Scenario to WorldSetup (for the reading from the world setup text file).
Changed package naming. Now we have a package per scenario.
Put world setup text files inside scenario package.
Generic way to generate a WorldSetup from a text file (see WorldSetup class). A similar way was previously used for Sokoban levels and is now used also for all other scenarios as well.
Ability to save the current WorldSetup set-up to a text file.
Support for multiple scenarios for one exercise: If a WorldSetup text file contains multile WorldSetups, a drop-down box is displayed at startup to choose one of the WorldSetups.
Added a title in the title bar.
Added Kara icon to frame.
Disable context menu for non-developer mode in sokoban.
Enabled wildcard (* and ?) filename patterns to find world setup files.
Switching to Java 6 compliance because of Greenfoot. Greenfoot is not able to use Java 7 at the moment.
Made some adjustments to have similar code as GreenfootKara.
Kara now has a stop() method to stop the simulation cycle. Now we can always use the run button.
Kara Sokoban contains now an example of alternative images (skin). See Kara Sokoban Solution.

Drag-and-Drop improvements: Enable or disable Actor dra-and-drop in World class.
Solved bug in context-menu: Sometimes an new ...() entry was in the context menu even if it is not possible to add such an actor at this location.
Solved bug in drag-and-drop: Sometimes when dragging an actor, the actor that is not on top was picked.
Mushroom glow when dragging: Updating the mushroom glow (on-target) whenever an object is dragged or a new object is created.
Removed restriction of max level 105 for the sokoban game (this was necessary for greenfoots online highscore)
