[Docs]: Relative URLs

[BenAlanSouthall]

It looks like the way to generate relative URLS would be to set the site deployment URL to be a simple forward slash. If that's the case, it would be good to add this to the documentation! Some other tools have a specific option and I wouldn't be surprised if some more sophisticated handling is needed, but if this works properly under WP2Static then a quick line in the docs would be great - or if otherwise there is a different way, then it'd be good to see this too. I didn't find anything myself.

Thanks!
