Initial (i.e. read only) support for RECURRENCE-ID modified incidence series.

Write support requires further debugging and/or compliance checks with respect to Zimbra;
there is no obvious reason why it should not be working but Zimbra fails with 409 when saving.
User interface support is mostly complete, with event links being tracked across deletes.
