Remove the assignment operator from a regular pointer to a RefCount
it is too easy too shoot yourself in the foot with it, other smart pointers also don't allow such assignments. If you do want to assign to a RefCount pointer, use reset(). ps: assignment between two RefCounts remains possible, of course.
