Bug 1109390 part 12 - Update IsPaused to handle pause-pending players as well; r=jwatt IsPaused is used in nsAnimationManager to detect if a newly created animation should be paused. It is also used inside AnimationPlayer::IsRunning which is used to determine what animations to send to the compositor (we don't send paused animations to the compositor). In all these cases we want to treat paused animations and pause-pending animations alike. This patch updates IsPaused to include also pause-pending animations. At the same time it renames IsPaused to IsPausedOrPausing to reflect the change in behavior. This patch also adjusts a few nearby one-line functions to put the opening brace on a new line since apparently this is what the coding style says to do.
