Add docpress

[dingo-d]

Added docpress as a default 'page' build for this repository. This generates a 'pretty' layout that is similar to what Tide has for their project.

Looks like docpress needs to be installed globally to run docpress s. Could it be run from npm scripts?

I've updated the readme and package.json with scripts to run it locally, without global installation.

I'll try running this on my windows machine tomorrow.

On my windows machine, it runs fine, both start and builds, although I cannot see the docs in the sidebar, which is weird.
