Fixed MATLAB bridge

MATLAB bridge.hpp was missing definition for Ptr<DenseOpticalFlow>
Merge branch 'master' of https://github.com/Itseez/opencv
DownhillSolverImpl::innerDownhillSimplex something looks broken here:
Mat_<double> coord_sum(1,ndim,0.0),buf(1,ndim,0.0),y(1,ndim,0.0);
nfunk = 0;
for(i=0;i<ndim+1;++i)
{
y(i) = f->calc(p[i]);
}
y has only ndim elements, while the loop goes over ndim+1
Updating missed defines in documentation

Updating missed defines in documentation. The new defines (in imgproc.hpp) state they have a prefix of COLOR instead of CV.
