fix compilation OpenCV with cxx11 under Ubuntu with clang and gcc 4.7

The labels of a model are now cloned instead of using Mat::copyTo, because Mat::copyTo leads to a crash with the Python wrapper. I need to further investigate it.

Added a simple CMakeLists.txt to the facerec_samples, which are not included in the samples folder. Makes building these samples a lot easier.

added openfabmap code, contributed by Arren Glover. fixed several warnings in the new versions of retina filters

updated Retina module code for more flexible parallelisation : TBB parallel for loops are replaced by opencv parallel_for_ wrapper... compile error corrected

updated code for more flexible parallelisation : TBB parallel for loops are replaced by opencv parallel_for_ wrapper

Retina module is now parallelized thanks to the TBB library. Speed increase expected on multicore plateforms

Issue #2231: Attempt to fix segfault, when copying labels. LDA needed to be updated to generate the Wrapper correctly.

facerec.cpp: Removed Original LBP wrapper, because it is not in use and therefore generates a warning.
