MessageQueue now correctly reports that an update is not required

[Problem]  The message queue always reports that it has messages even if it does not.
[Cause]    The sceneUpdate counter never gets decremented to 0. This causes the update to run
           every time.
[Solution] It was being cleared within a for loop where messages are being processed, it should be
           outside this loop so is cleared if there are no messages.
