Scores management

[chlablak]

Add score for each player session.

Score can evolve in differents ways, for exemple when the player:

• clear a level (+10 +/- ...)
• rewind a movement (-1)
• and other...

• clear a level (+10 +/- ...): Does +/- mean we need to find optimal path for each level?

[chlablak]

this are for exemple only, we need to fix how the points are counted

[AlainHardy]

After reflexion, I don't think it is necessary to have the optimal path. For exemple, we just have to fix a certain amount of point for each level, and after each player's move the level's score is decremented. When the level is completed, the score for the level is added to the actual total score of the player.
