Time of day

I really miss this feature from my old TiVo unit. TiVo had a hack where you could display the time of day in the bottom corner of the screen. Google TV will show the time if you press Home but it overlays the home screen and dims the video so It's very disruptive.

I jumped on the opportunity and wrote this change

That shows the current time in the bottom right corner if you press T on the KB. The display will remain there until you press T again and is persistent in preferences.

I copied the code from TextClock which was introduced in API 17 because the existing DigitalClock view has a "second" ticker which is too distracting IMO.
