Added feature that allows control over the CPU time which is given for transcoding purposes. Two configuration parameters, TranscodingSleepEveryNumFrames and TranscodingSleepUs have been added to config.xml. If both parameters have non-zero values then the transcoding thread will sleep for TranscodingSleepUs microseconds every TranscodingSleepEveryNumFrames which are transcoded.
