fixed iterations>1 case in morphological operations (bug #2348; thanks to Andrei Zaharescu for the fix)

Should now automatically detect it during Android build

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.

Search keys for /proc/sysinfo updated.

Camera connect->disconnect->connect leads to sigsegv.
Apply properties method reimplemented.
