* Calendar: fix holidays are displayed one day off for eg. Austria, Slovakia, Australia (from iCloud)

Caused by no real floating date support in EGroupware and defaulting to UTC, if no timezone specified, because Horde_Icalendar does not report datetimes postfixed with Z as UTC.
Fixed now by not using UTC workaround for date (not datetime) values.
Also implemented default duration of one day for dtstart as date and no dtend/duration given.
