- groups can now be selected as participants again
- groups need to have calendar run-rights, to be selectable in the calendar (as it was in 1.0)
- groups will NOT be enumerated as users anymore
--> new or removed members are taken into account as participants
- error messages: if no participant selected or startdate behind enddate (no more automatic swapping)
- pushing the version to 1.2
- if an endtime leads to a duration biger the the difference between day-start and -end, the day-end from the user prefs are ignored, else it would never find a free time
- using one selectbox for the duration with an extra item 'use enddate', to be more intuitive about duration or enddate is used
- selecting a fitting search-frame for new searches, not just one week
- for existing events, the own event is now excluded from the busy-time
- a warning is given, if the freetime search is called for a recuring event: Only the initial date of that recuring event is checked!
