Changes in kalziumglwidget:

Changes in kalziumglwidget:

- added FPS (frames per second) counter. Enable it by #defining
  USE_FPS_COUNTER. (Currently enabled).

- added option to cache the rendering of the molecule using a GL display
  list. This improves speed, especially for rendering complex
  molecules; I have measured a speed increase above +35% in some cases
  (depends also on the style and the widget size). Enable it by
  #defining USE_DISPLAY_LIST. (Currently enabled).

Change in latticedialog:

- I allowed myself to comment out ui.glWidget->update(); in
  LatticeDialog::slotUpdateView() because normally this is being
  taken care of by slotSetMolecule; also I think that for a GL widget,
  one should call updateGL() instead of update(); not 100% sure here.
  Carsten, I didn't see the "blank widget" bug in the lattice viewer;
  have you already solved it?
