Changed a tf frame that was altered for the robot.
Readded an old tf frame as it might be needed for older simulation models of PR2
Corrected line lengths
Corrected threshold usage for occlusion reasoning; was detecting no objects
Updated .gitignore
Explicitly included `urdf/model.h' because it is not included implicitly anymore
Depending directly on `pcl_ros' as otherwise necessary headers are missing in groovy
Changed the function `reconstructMesh' so that it works with the new PCL version

Type names for the new PCL version and the overall process of calculating a convex hull changed. This is now reflected in `triangulate_pcl.cpp'.
Ha! Finally found this missing manifest dependency.
PR2-projection-process-module now add their own implementation of the predicate cram-plan-knowledge:projection-running to signal regular process modules that they are running.
