Dismantled Singleton pattern of PowerSaver The instance-on-demand didn't really work, since we needed explicit control over this object's destruction to ensure the timer is stopped when launching an application. And trying to combine getInstance() with explicit external delete was just ugly. 2014-08-14 10:47:05 +03:00			`PowerSaver();`

Various cleanups in PowerSaver Use nullptr instead of NULL, evaluate pointer as bool where possible. Declare the timer callback as a friend function so the methods it uses can stay private. Initialize screenState to false; was uninitialized which means that an initially blanked screen might not be unblanked. Force screen enable in constructor instead of when timeout is set. Add removeScreenTimer method. Include C++-ified versions of the C headers. 2014-08-14 10:16:13 +03:00			`void removeScreenTimer();`
