Export recurring events and build ICS files for configured exports
Summary:
Ref T10747. This:
- Exports recurring events properly, with RRULE + RECURRENCE-ID.
- When exporting a part of an event series, export the whole series to ICS so it is represented faithfully.
- Make the subscribable URL for "Export" objects work.
Test Plan:
- Downloaded the ".ics" for a normal event, imported it into Calendar.app and Google Calendar.
- Downloaded the ".ics" for a recurring event, imported it into Calendar.app and Google Calendar.
- Defined an ".ics" Export of my events, subscribed to them in Calendar.app.
- Edited an event in Phabricator.
- Hit ⌘+R in Calendar.app, saw changes. (MAGIC!)
- This export included recurring events, which appeared the same way in Calendar.app and Phabricator.
- Can't import into Google Calendar from my local install easily since Google's servers can't hit my laptop, but I'll test once we deploy.
