Added a options panel.

* Added screenshot action that saves two images: one of the main
  view (plot + splat) and one of the bottom view (bar chart)
* Added methods/signals/slots to Scatterplot for handling glyph sizes
* Added methods/signals/slots to VoronoiSplat for handling the
  alpha/beta parameters, which are now also no longer fixed
* Options panel:
  - glyph sizes of both CPs and RPs
  - splat opacity
  - splat parameters (alpha & beta)
  - color scale combo box currently does nothing
