Paddy a574e93359 Escape and fold the iCal export, serve it as text/calendar, add subscription links ...

- iCal export: RFC 5545 text escaping for SUMMARY, DESCRIPTION and LOCATION,
  line folding at 75 octets (UTF-8 aware), CRLF line endings, and
  Content-Type text/calendar instead of the inferred text/html. A line break
  in a description used to end the property early; the new calendar
  frontend has a multi-line description field.
- formatDate no longer shifts the event's end date in place.
- GET /calendar/events/subscriptions: the iCal URL of every calendar, with
  its shared password where needed, for the calendar app's "Abonnieren"
  dialog. Editors only (requireAppAccess('calendar')), the shared password
  is not accepted there, never cached; calendars without a configured
  credential are left out.
- Tests for both; documented in docs/calendar-ical.md.

Backwards compatible with the current Angular calendar app.
