Was broken in my previous PR, since pointer graph serialization was
enabled by default, leading to deserializationFix triggering on netpack
apply.
Cleaned up / clarified code
- Removed (most of) boost filesystem namespace usings
- Replaced boost::filesystem::fstream with std::fstream and different
constructor that should be available on any plaftorm
Disabled the following (for MSVC only) that couldn't (or shouldn't) be fixed.
4003: not enough actual parameters for macro 'identifier'
4250: 'class1' : inherits 'class2::member' via dominance
4251: 'type' : class 'type1' needs to have dll-interface to be used by clients of class 'type2'
4275: non dll-interface class 'type1' used as base for dll-interface class 'type2'
