Patch to add support for DTEND

[branson]

Created a patch to add support for a dtend field in icalview:

We don't use duration here.. but use ganttcalendar plugin and therefor use due_assign and due_close; So I added support for start/end vs start/duration. This works well for 'leave' type tickets and 'task' type tickets.
