[kronolith] private events in shared calendars through ics

[munzli]

hi
i noticed that if you look at a shared calendar with an ics client 
throught the rpc.php that the user is ignored and it only checks for any 
authorisation?! because subscribing to calendars from other user shows 
the complete events even if they are private. in the horde web frontend 
they are correctly shown as private events. how is it possible to get 
the ics to only show your personal calendar with private events and 
shared calendars with a "private event" kind of title?  this is very 
very important to keep the privacy of our users.

thank you for the help
