Use make_shared in visualization

[wmtan]

"auto thePtr = std::make_shared<MyClass>(...)" is preferred to "shared_ptr thePtr(new MyClass(...))" because it saves a memory allocation. It allocates the shared_ptr and the pointee in the same allocation.
This PR changes the places in visualization that did it the suboptimal way. To do this, it was necessary to replace the use of boost::shared_ptr with std::shared_ptr, which was done throughout visualization.
