Classes, Objects Properties etc. in the ToC are not ordered alphabetically, e.g.:

Also add a bit more space between entries so multi-line entries - long names - are distinguishable from two entries

Just a note after looking at #122. Right now the ToC is sorted by the fragment and page content is sorted by full IRI, which leads to the ToC and page not being in-sync.
