Improved death screen

While struggling with the inventory system debugging/polishing, I've taken some fresh air by improving the death screen. It's now splitted into four subscreens :

• a summary with some stats on the player
• a list of achievements
• the player inventory when he died
• the highscore table

Achievement are rewarded in certain circumstances, for example when you open all the chests in a dungeon. They give you additional XP points during the game and improve your score.
