Add a switch to use the last object of the average track center when tracking objects.
Fix a bug in tracker, track->total_weight was not initialized properly. It would seem that this could have caused all kinds of issues with the tracking.. Not sure why I did not catch this one earlier..
Change averager to also total peak area and peak sum. Previously it was only totaling the peak height.
Change averager to not total sum, as this field is used to record the fitting error in 3d-daostorm. Now it is not averaged, it is the value from the first localization in the track.
