replace StatisticsFPSfactor that needed to be changed with FrameTime to a simpler true or false Normalized55FPS that is now TRUE by default. Incorrectly this commit also contains changes that should had their own commits: changes to heartbeat time control ant to gathering and calculation of related statistics.
