Add start/end time fields to CalendarEvent (#28) (#29)

## Summary
Closes #28.

- Add optional `start_time` / `end_time` (`TimeField`) on `CalendarEvent`
- Expose times in Django admin list + form
- Replace hardcoded calendar template times with `time_range_display`
- Add migration `0013` and unit coverage for time formatting

## Test plan
