When a user declares their participation in an Event (Space of type Event), there should be a dropdown menu that proposes to add the event to their calendar (at the moment, by downloading the .ics of that event, with some extensions in the future for calendar integration). For Spaces of type Program that have Events inside, there should be a "subscribe to the events" button that allows the user to subscribe to the calendar and get all the events for it automatically (as opposed to per-event).
