Marcel Raad 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.
