Multi-day events

[zenhack]

I would like to be able to enter an event into my calendar that spans more than one day, e.g. a camping trip.

I think this is not really a separate issue, so I'll just note here: I tried to put an event in that started at 11 PM and ended at 12 AM, and the weekly view was VERY confused, which makes sense, considering I must've technically submitted an event that ended before it began.

Yeah, I'm not surprised the weekly view did something weird with that. Probably we should do some validation to keep you from doing that in the first place.
