Map movement, 15x15 puzzle, Skip Animation and Saving System between versions

Hi, pretty big update today with some new features and fixes.

Update :

- Map Movement: 

You can now advance in the puzzle selector to continue your progress. I know that if you spam the move button then you'll go pretty far, the problem is already fixed but I didn't rebuild just for that, it will be fixed in the next update.

- New 15x15 puzzle : 

The first puzzle is available in Section 2 - Puzzle 1 (The next puzzles in section 2 are not available yet).

- Skip the end of puzzle animation :

 At the request of some feedbacks you can now skip the end of puzzle animation by a simple left click.

- Improved save system: 

Automatically made saves are now automatically transmitted from one version of the game to another. If I post an update then you will be able to continue with the last content directly. It will take some more thought if I want to change the order of the puzzles later but for now it will be more enjoyable for you.

Thanks for reading!
