- fixed fatal error if participant is no account
- if participant has no email use a pseudo one: noreply-$uid-uid@egroupware.org
- do not add account of calendar as participant (readd it in ChangeMessage)
- use calendar_boupdate::update() instead of ::save() to get notifications
- fixed fatal error call to member function ->format(), if event has an exception
- ChangeMessage now searched contacts for participants and always re-adds resources (everything but accounts, contacts and email)
- some more timezone specific fixes
>>> none of the above is tested, as my iPhone charges no more and battery is now flat :-(
- direction back is implemented (and tested) but not yet used, as storing events is not yet implemented
- timestamps are passed to zpush now in servertime, which it converts internal to UTC times
- recurring event information is now correctly supplied (thought we do NOT yet deal with virtual exceptions!)
--> next step would be storing events synced in from the client
