#33 add_registration_code behavior is inconsistent

[Jason Kankiewicz]

The behavior of the "add_registration_code" method is inconsistent between the pyplusplus.decl_wrappers.class_wrapper.class_t and pyplusplus.module_builder.boost_python_builder.builder_t types.

pyplusplus.decl_wrappers.class_wrapper.class_t.add_registration_code doesn't require a "def" member function call to be prefixed with a "." or suffixed with a ";".
pyplusplus.module_builder.boost_python_builder.builder_t.add_registration_code does require a "def" free function call to be prefixed with a "bp::" and suffixed with a ";".
It would be nice if the add_registration_code method would always add the necessary prefix and suffix as necessary regardless of which object it is an attribute of.
