Calender export buggy for recurring events with exceptions

[aschloegl]

We are using ical-export (the calender export function) a lot.  Recurring events with excepts does not consider the exception.

The issue can be repeated in the following way:
- book a series of events
- modify or delete a single instance of this series.
- export the calender of the resource or schedule to ical.
- import this ical file into your calendar client (Outlook, Mozilla lightning, etc.)

A deleted event of the series will still appear, and if the event is modified it appears twice - once in the original definition and once as a new event. Thus, the calendar export is broken. This is tested on 2.1.4 and the development version from a few days ago.

As a fix for this problem, I suggest not to use the recurrence rule for exporting to ical, but export everything as single events.
Since this is only one-way data communication, and an update of the calender requires a new ical-export of the whole calendar, it is ok to lose the recurrence rules in the process.

That's an interesting idea. I'll see if I can fix it.

That is fixed in revision 1562.

In order to fix the LOCATION field, revision 1563 need to be applied, too.
