site 1.6.0 (local): four mods stable, the rest experimental; builder ticks all and warns

- Stable: extended BPM, boot text, LED animation, cue colours; every other mod
  experimental (main page, docs, builder).
- Builder: every mod ticked at the start; a red warning across the top: for
  home use, not for clubs or gigs.
- Intro: the emulator links to QEMU.
