Add content when player uses fast sort

On Liv7b, add some extra puzzle or easter egg if the player solves it using a n.logn algorithm instead of quadratic.

Just use something similar to the extra jen puzzle, checking game ticks after finished? Should be really easy, just need to create a new liv email congratulating the player

For now it is not possible to differentiate n.logn from n² (because of the overhead). My n² solution took 3442 steps and the n.logn took 3220. Maybe in the future we can increase the size of the list to notice a greater difference. Postponing this.
