[FOSDEM] Sojourner schedule webapp update

[Jarek]

Hi everyone,

I am happy to announce updated version of Sojourner-Web FOSDEM
conference scheduler: https://sojourner.loomchild.net

It's a progressive web app that you can add to you phone home screen.
Once installed it works fully offline. It allows you to select your
favourite events before coming to the conference and can show you the
room open/full status during the event. Latest features include ability
to share data between different devices and event search.

Hope you'll enjoy it - any feedback is welcome.

See you in Brussels next weekend!
Jarek Lipski
