44d57a1d8b Fix: prevented the binding illegal temporary to optional<const int&> 
Older MSVC versions add illegal temporary when you want to assign from const integral value.

4e7405a233 Sane swap() for rvalue-aware compilers 
When we detect that compiler supports rvalue references, we implement swap() in term of moves (as intuition suggests).
Otherwise we fall back to old tricks with default constructor+swap

53e53171c4 none_t is no loner constructible from literal 0 
This caused problems because:
optional<T> o = 0;
always worked. But often it would create an uninitialized optional.

This change makes the library usable (again) on C++03 standard library
implementations where <stdexcept> doesn't imply inclusion of <string>,

5e59e10f93 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.

c7cf80e5df 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.
