Schedule Symbian active objects with a round robin scheduler

Each call to QEventDispatcherSymbian::processEvents allows
pre-existing active objects with priority >=
CActive::EPriorityStandard to run once. Active objects with lower
priorities can only run if no higher priority active object has run.
