Add support for URLs relative to context root
Setting `RelativeURLs` to `true` will make all relative URLs in the site *really* relative.
And will do so with speed.
So:
In `/post/myblogpost.html`:
`/mycss.css` becomes `../mycss.css`
The same in `/index.html` will become:
`./mycss.css` etc.
Note that absolute URLs will not be touched (either external resources, or URLs constructed with `BaseURL`).
The speediness is about the same as before:
```
