Release v2.0.2

The default HibernateDelaySec is now 1440m.

This is 24h. We assume the following scenario.

A user uses a PC every day at the same time. For example, he turned on the PC at 9:00 AM and closed the lid at 7:00 PM. With the 24h HibernateDelaySec, PC doesn't hibernate at 9:00 AM of the next day. So, the resume is quick.
Assume the user takes a rest on the weekend. Then, the PC hibernates at 7:00 PM on the weekend. Therefore, the user can conserve battery power on the first day of the weekend.
