+=====================================================================
+
+Some crashes avoided, notably if loading a manually edited saved game
+file, and a better tiles look on non-square grids, that should be all
+the things important for users. From the technical side, the internal
+representation of the board changed, to make it less error-prone, and
+many parts of the code have moved around. Some tests were also added.
