Stop calling UpdateSystemActivity in places where we hold power assertions that achieve the same effect

[Mark Rowe (bdash)]

In a couple of locations related to fullscreen media playback we periodically call UpdateSystemActivity.  There’s no need to do this on SnowLeopard and newer as the power assertion that we hold to prevent display sleep also prevents the screensaver kicking in.  It doesn’t prevent the screensaver on Leopard though, so we’ll still need to call UpdateSystemActivity in that case.

I nuked the unused variable name from here.

Missing blank line after this.

I prefer kCFAllocatorDefault

Does this branch need an UNUSED_PARAM(reason)?

> +void DisplaySleepDisabler::systemActivityTimerFired(Timer<DisplaySleepDisabler>* timer)

No need to name the unused parameter here.
