Refactor storage grid, cage, cell

[GoogleCodeExporter]

Current storage mechanism for grid, cage, cell needs refactoring due to 
increasing number of versions.

Example:
    public static final String SAVE_GAME_GRID_VERSION_01 = "VIEW.v1";
    public static final String SAVE_GAME_GRID_VERSION_02 = "VIEW.v2";
    public static final String SAVE_GAME_GRID_VERSION_03 = "VIEW.v3";
    public static final String SAVE_GAME_GRID_VERSION_04 = "VIEW.v4";
    public static final String SAVE_GAME_GRID_VERSION_05 = "VIEW.v5";

The version number can be replaced with the revision number of the app instead.
