Fix: reorder initializers
Fix: remove debug messages
Add: 2D GrabCut application
Fixed bug in passthrough filter

- Points on filter boundaries were included into inliers (i.e.
  'setFilterLimitsNegative (false)') and outliers (i.e.
  'setFilterLimitsNegative (true)'). Now points on the boundaries belong
  only to the set of inliers.

Simplified pcl::Registration::getFitnessScore()

getFitnessScore() is implemented quite complicated. To transform the input,
transformPointCloud() can be used and the point-to-point distance is allready
given by nn_dists[0] returned from nearestKSearch().
