reloadDay method problem

Hi Devin,

I use the TKCalenderDayView over the addChildController method of a parent controller -> Segmented Control.
The TKCalendarDayTimelineView: didMoveToWindow method is called everytime if I switch between the segmented controls. This causes a few troubles, like some methods of my TKCalenderDayView are called to update some appoinments.

Now the reloadDay method is only called if the events array is empty.

So if you want, feel free to pull my commit.
If you find a better way to solve this problem please let me know.

Regards,
