Make RefCount<> more sensible
the previous version of operator*() made no sense. E.g., it violated the invariant (*ptr).foo <=> ptr->foo. The dereferencing operator now returns a reference to the pointed-to object, rather than a pointer to it. I also added a bool conversion operator, which can be used in testing the NULL-ness of the pointer. Anyone wondering if that could be done in a simpler way is encouraged to read <http://www.artima.com/cppsource/safebool.html>. And, finally, I removed the mutable flag from the m_data member, since it does not need it.
