TOOLS/stats-conv: rewrite for pygtgraph 

matplotlib is pathetically slow, which makes using stats-conv.py to view
dumps longer than a few seconds a huge pain.

pyqtgraph is slightly faster than matplotlib. Other than that, it seems
to be worse in every aspect (at least for plotting), but such is life.
