Fix warnings with gcc 4.4 in C++11 mode
...
GCC 4.4 has support for an early draft of rvalue references. When compiling the conforming code it produces warnings such as '../boost/optional/optional.hpp:152: warning: returning reference to temporary'. In order to fix this regression use a special implementation of move(), similar to std::move() on this compiler.

Use BOOST_EXPLICIT_OPERATOR_BOOL for optional
...
I often have the problem that when I change a std::wstring to boost::optional<std::wstring> and the variable is used as a parameter with Boost.Format, the result silently changes from the string contents to "1".
This change prevents implicit conversion to bool if the compiler supports explicit conversion operators.
