Example deployment: link to 'posts' is broken

[dholbach]

On https://sbruder.github.io/spectral/ the link to "posts" is broken. It works locally and has worked in the deployment before.

Looks like the posts URL should be https://sbruder.github.io/spectral/posts/ I think this is due to the site using absolute instead of relative URLs. I think this can be fixed by changing the baseURL in the configuration file to https://sbruder.github.io/spectral/.

I rolled the change back for now: #32
