[kronolith] How to refuse overlapped events for some calendars ?

Quoting Patrick Abiven <patrick.abiven at apitech.fr>:

There's at least one ticket on bugs.horde.org for checking conflicts  
when creating a new event. If I was going to implement I'd follow this  
rough outline:

- Implement checks for conflicts when creating/editing events
- Resources should be implemented as attendees, not as calendars (you  
want to be able to "invite" both a projector and a meeting room, for  
example). So do some sort of virtual account implementation, where  
administrators can create and manage resources.
- When a resource is invited to an event, it must be free for the whole event.
