GUI-Macro addition

added method to the GUI Macros which can close any given window (this is
different and independent from the CloseListener method)
multiple fixes & updates to results tab

CSV download buttons seem to work correctly now; raw data button is now
functional, though it still provides null information; labels and
filenames added above preview images in results tab, images also
restricted to specific size so histograms align properly; all histograms
now have zoom functionality
