Divestment lifelines on select clocks

[shwaydogg]

We need a way to 8ish have specific lifelines show on specific clocks.

Changing that API URL on those clocks in the prefs and letting the API handle the rest works as a simple solution.

Each clock with the "flag" in the api url would have all 8 extra lifelines

Can we use a unique device string instead of a flag? Seems more conducive to a [future] static json API. Any objection to something like this? https://api.climateclock.world/v2/portable_m4_divestment/clock.json
