Add calendar subscription links to subgroup meetings
Three possible implementations here:
- Some kind of cron job that filters agenda into
.ics
files - Something similar integrated into the docs
- Reorganize indico into categories and use the indico links
I'm a big fan of 3 because it's less technical work for us, and also lets us appoint managers for the categories. I think @pgadow was reluctant, although I promised that that wouldn't break anything in existing indicombs. Other thoughts from @svanstro (the other owner of this repo)?
