Mike Lockwood c22404a4e7 Implement new notification LED blinking logic:
1) Do not pulse notification LED when screen is on.
2) Pulse once on new notification if Settings.System.NOTIFICATION_LIGHT_PULSE is false,
   otherwise pulse persistently while screen is off.

Fixes part of bug b/2238250 (trackball should pulse occasionally to indicate new email)
