Site 1.1.0: beat jump in the builder, version and changelog, key colours

- Beat jump (experimental) on the mods page, in the docs and in the builder
  (needs hot cue keys; dependencies are ticked and unticked as a chain).
- Key notation 1.2.0: keys in their Camelot wheel colour, also in BROWSE.
- Version badge at the top with a changelog; every mod's version on its
  card and in the builder. make_builder_data.py writes assets/versions.js
  from tools/changelog.json and the mods' versions and stamps the pages'
  CSS and script links with ?v=<site version>.
- The generator keeps a changed copy of the UTILITY table as the user's
  own table plus our bytes (beat jump renames an item).
- Upcoming: quick search, USB auto load and phase meter reverse (in testing).
