Add levels

[ojasva]

We could probably add different levels, once we are done with the level 1(beginner), we move on to the next one i.e level 2(easy) and so on.

Automatically start with the next higher level isn't something I'd like. What if I came to the conclusion that "Easy" is the best I can do. Then I'll always have to change the difficulty back to "Easy" after avery game.
The ticket topic is misleading.
