Images are broken in the discovery book

[japaric]

At least in the bookshelf version. See:

https://rust-embedded.github.io/bookshelf/discovery/04-meet-your-hardware/index.html

The standalone version of the discovery book does show the images:

I was playing around with linkchecker tonight to see if I could see why it doesn't detect these missing image URLs. It seems like it treats the absolute links as external links so doesn't bother to check them. I was able to get it to detect the bad links by using this command line:

linkchecker --ignore-url "http.*" --check-extern doc

I used the --ignore-url option too since linkchecker gets a bunch of internal errors if it actually tries to validate links to external websites when I ran it on my Ubuntu VM.

I have just created PR #9 to address this issue for the bookshelf repository as well.

This is now fixed.

Thanks @adamgreen!
