Improvements related to ColorScale and screenshots.

* ColorScale: now a pointer whenever needed. main() takes care of
  updating extents
* New class DivergentColorScale: works specifically for divergent
  scales, always has 3 colors as input: negative values, 0, positive
  values
* ManipulationHandler: ProjectionHistory no longer needed
