Minesweeper game

[identity2]

Completed the prototype of the Minesweeper game.

Players can navigate to the Minesweeper game by choosing:
School Scenario -> Sure -> Sure -> Do you have condoms? -> Never mind, let's just have sex.

For now, there is only a single contraceptive method. More contraceptive methods should be added later.

The game looks good. My comments/questions:

1. For some reason, the deployment target is 10.0 in this PR which is a change. It probably should be 9.x. Are you using some iOS 10-specific feature?

2. I suggest making the gameIndex (MiniGameViewController.swift) an enum to be more transparent about what the index means.

3. There is an small box in the lower right of the game. Is that from SpriteKit? Doesn't look like it is for the user.

1. Think I accidentally changed that, I changed it back to 9.1.
2. Yes, enum is way better than plain Int indices (I always forgot to use enum when I should 😅). Changed that.
3. The debugging box is disabled now.
