📄 Add native support for Indiepaper cleverdevil.io

@cleverdevil Whoa, indiepaper is cool! Guess I need to start experimenting with Aperture now.

@alans thank you sir! Yes, you should :) If you don't have or want Aperture, you can also just create a separate site that supports Micropub and use that as your target.

@cleverdevil I thought of that, too! (Making a new site with micropub and targeting it.) And, say, since I'm not using my hosted micro.blog blog ... idea: I wonder if I could re-purpose that as the micropup endpoint for indiepaper. That could be cool.
