[Owncloud] Birthdays from contacts to calender

[Daniel Wunderlich]

Hello,

first of all, I want to thank all the hard-working developers of 
ownCloud! You created a really impressive piece of software -- thank you 
and rock on! :o)

I upgraded from version 3.0.3 to 4, obvious without any problems. I had 
no times to test all the new features, but I will do this the next days.

I saw that birthdays of contacts now appear at the calender of the 
web-frontend as gray-colored events, too. That's a nice little feature I 
was looking forward to.

Now my question: Is it possible  to sync the birthdays (or rather the 
corresponding events) via caldav? I use Thunderbird, which already syncs 
finde with my calenders, but the birthday-events are not synced and only 
displayed at the web-frontend.

Regards,
Daniel
