elm-tutorial-extended

I will try to implement the "Improvements" section of the Elm tutorial. The features that will be implemented are :

• Add player
• Delete players
• Change player name
• Show error messages
• Optimistic updates
• List of perks
• Show perks for player
• Validation for player name when empty
• Search box for perks
• Tests
• When deleting a player delete associated perksPlayers

I'm currently doing my first steps to the magical world of Elm-lang so there is a chance that my code is a mess.
