Add some scoring system

[abejfehr]

No scoring system exists which gives nobody the incentive to beat the game. We need to add some kind of scoring system to change that.

Scoring could be based on time to complete a level, or attempts to complete a level.

The problem is that once a user figures out how to complete a level, they can reset it and just finish it quickly, giving them a good score. If you don't reset the timer when the push the reset button, the user can just do it by refreshing the page. The only other way is if the timer was server-side, in which case we need a server 😜
