I need to craft UIDs to make birthdays from turba work.

$ical->addComponent($event->toiCalendar($ical)) seems to trigger a very 
deep recursion for birthdays - Events with start date and yearly 
recursion, but no real end (in data, at least). But only from turba, not 
for kronolith native events.

How to reproduce:

$app = Horde_Registry::appInit('kronolith');

$driver = Kronolith::getDriver('Horde', 
'contacts/birthday/13Q5VRmDqoeMFBOHEJKk5h_');

$event = $driver->getEvent('_contactstbNyQSp4mS7WJTB7hMqDWs7');
$event->loadHistory();
print_r($event);
$ical = new Horde_Icalendar('2.0');

$icalEvent = $event->toiCalendar($ical);

-> looooong and deep recursion until oom.


This is probably because the "Horde" Driver does not provide uid's for 
its events.

http://www.kanzaki.com/docs/ical/uid.html

Looking at the DB, I have long (113 chars) hex strings, uuids, and 
uuid@host formats as well as strings like KOrganizer-Something.

Using event->calendar @ $event->id would produce

contacts/birthday/13Q5VRmDqoeMFBOHEJKk5h_@_contactstbNyQSp4mS7WJTB7hMqDWs7

which looks about as unique as a native kronolith uid.

However I am not sure if any app would present the same timeobject using 
the same id differently to different users. I don't think so.
