Title: Changes to tutorial cornerDetector_Demo.cpp to prevent Seg faults.

1.myHarris_dst.at(j,i,1) was giving segmentation fault.Not sure if that is a bug or happenend just for me.But made a few changes to correct that.Using myHarris_dst.ptr(j,i) instead.No more seg faults.
Have a look.
2.Changed char* to string for window names
