Do you want a "set base url" plugin?

Context

Sometimes you have some markdown content that is intended to be hosted at http://www.example.com and so it has things like images with relative links, like /images/cat.png

But sometimes you want to show rendering of this content in other situations. eg Maybe you are providing a nice CMS for people to edit this website at http://cms.example.com or even http://third-party-cms.com/project/example.com

Now, all your links are broken!!!

Proposal

A new "set base url" plugin.

You configure it with a base url like http://www.example.com and it rewrites all URLs like /images/cat.png to http://www.example.com/images/cat.png

Now the rendered HTML can be shown on http://cms.example.com and links work!

Could also be called "make URLs absolute" maybe.

Tasks and updates

I've already started on this and am happy to contribute it here if it's wanted?
