Take images out of source control

This is cool and I like it a lot. 👍 I'll give you a tip I wish I was given way back at the start of ALE.

I recommend that you upload your images into a dummy GitHub issue and link to the images stored on GitHub. Otherwise the binary files will inflate the size of your Git repo a lot. You have only just pushed your first few commits, so now would be a good time to rebase your commits to remove the images. There are some image files in very old commits of ALE, and because there's so much history now I can't ever remove them. I just recommend people pull the repository with only the most recent commit to reduce the download size.

Thanks for pointing it out - I'll take it into consideration.
