Display event date ranges properly

[ky28059]

Not sure if we need to parse this ourselves, but iCal date ranges are typically given to us in a day-by-day format, where if an event was taking place from Aug. 5 - Aug. 7 it would give us 3 day-long events on Aug. 5 - 6, Aug. 6 - 7, and Aug. 7 - 8. This is misleading as displaying the day-long events makes it look like the event is only from Aug. 5 - 6 for example, when its really from Aug. 5 - 7.

I think homework central might have had code to help with this? We'd also need to rework our logic for displaying an event on a certain day to correctly parse day ranges.
