[Evolution] over-midnight entries

[Carpet Nailz <carpetnailz researchintegration org>]

A nice feature would be an easier way to enter over-midnight entries:
that is, something that starts at 11pm and goes to12:30am. Right now, it
seems that one has to change the day on the second part of the entry and
the entry then goes into the "All Day Event" category. We're not really
dealing with "all day" events here.

Would it be possible to have the entry work automatically and just post
the event in the 11-12pm portion of the first day and the 12-12:30am
portion of the next day? For example if one enters 11:00pm and then
enters 12:30 am, the system would "know" to automatically post the event
correctly in the two different days?
