Add option to force https on redirect url

I'm using this patch, the patch is for the dev branch.

https applied to file url.

I wonder why we need to generate an absolute URL? Drupal used to do that, but these days would typically do it via a root-relative URL. I wonder if changing over to that would be simpler.

Let's see what happens with this change.

Tests are still passing then, I'm inclined to merge this.

Yeah, let's merge it.
