Fix rendering; apply consistent html formatting

[decentralgabe]

The build for the previous commit failed with a set of errors such as:

    No ID for section: 'H3'.
      {
        name: 'structure.section-ids',
        section: 'document-body',
        rule: 'headingWithoutID'
      }

to remedy, I've added identifiers for each heading tag. I've also applied a formatter to the HTML so that it is consistently formatted. Sorry for the large change, it is mostly shuffling deck chairs around.
