Add new practice exercise `game-of-life`

[jiegillet]

It's been a while since the last exercise, it's always a pleasure.

I watched the recent 48in24 video about the minesweeper exercise, and I was a bit frustrated not to have seen a higher-order solution using matrix convolution kernels or something, and since this exercise is also about counting neighbors, it was the perfect way to pass my frustration :)

Excellent suggestion :)

We have a seemingly dead link:

José Valim, the creator of Elixir, explains in his 2012 conference talk how he built the language for applications to be:

But actually the link works. Maybe it's just an anti-bot policy... What do we do in those cases?
