changes to qPCL: bug solved in MLSsmoothing with clouds with colors, now used OpenMP implementation when possible. Load and Save PCD files now can handle sensor positions. Added constructors to ccGBLsensor and ccsensor, now when cutting or cloning a cloud the sensor is copied along with the cloud. Fixed ccCustomObject type.
