opencv: grabcut: Ported to OpenCV version 3.1

Browse source 
cvarrToMat() is added because it is compatible with all versions of Opencv
and using the class Mat constructor is eliminated, because is deprecated
in 3.X versions. The use the using namespace cv because is called some
functions many times. This keeps compatibility with 2.4.
