Title: Calendar Overlapping Intervals

Calendar can now handle overlapping intervals from event spanning multiple days to multiple years.
Both the busy bars and months day view work.

This still feels a little slow on the device, I suspect we need to make day rendering async and make some tweaks to the new interval tree.
