DayRemain 2.4

I delete the countdown display by icon badge from version 2.4.
I changed the notification center to notify the countdown.

---------------------------------------------

The remaining days of the event which is registered in the list, is counted down with the message to Notification Cente.
And "lapse of days" is useful, too.

- You can confirm "days remaining" or "lapse of days" on the list.

- It posts to Notification Center that countdown ends. When an application is activated, the following countdown is begun.

- Countdown of 60 days or more in order to continue to display the badge posts to Notification Center 60 days.

- Days from today it is inspected simply in the event edit view.

- It can delete the list with the flick.
