normalize readme with .verb.md, run verb 3

- generated with verb 0.3.0
- normalize .verb.md (btw, found bug/idea, will open issue in verb)
- move `markdown-utils` at the top, lol

Yeah, verb 3 rulz :) But I cant agree with that `assemble` and `verb` share almost same codebase and exact same api. I think better will be to build assemble on top of final verb (0.3.0) and extend it with what needs for assemble.

Another fact, for me, is that verb/assemble continue to be too slow, LOL. 10-20ms for one simple readme, wtf? You continue to use `glob/globule` and `*Sync` methods. `globby` is almost good, but miss things from your `matched`, that in other hand is fully sync by default, which sucks.

I know this topic is not for here, but now appear in my mind.
