Assignable fixes are based on those used by C# std::vector where the
default wrappers work if there is no operator== available in the
template type. Enhanced wrappers are obtained via a macro:
SWIG_STD_LIST_ENHANCED(SomeNamespace::Klass)
%template(ListKlass) std::list<SomeNamespace::Klass>;
Remove bool specialization (left over from the original std::vector
wrappers).
Add in missing typedefs.
