Level pack released

As anticipated, we prepared a full set of new levels for our last game Charon's Obol.
Just remove/rename the existing level folder and unzip this in the game directory.
Please take care of backup&remove the file game001.sav in save folder in order to reset the game.

Just as reminder, five levels from the original set have been modified in order to make them winnable with gold medal. Details in this post.
