Bug 34900: (follow-up) List alphabetically and tidy ups

Listed in alphabetical order (except for Koha, which is listed
at the start).

Tidy ups and consistency changes:
- end of each entry: remove full stops
- separator between software and license: use a colon
- headings for software/library name: use sentence case
  unless a noun, abbreviation, or the actual software name
- http and https: use https where site uses it
- URLs: update where required
- license names: use consistent full names with title case
