#371, #368 Moved fake manager creation and initialization into the proxy generator (occurs either on the first virtual member call within the constructor or after the constructor has been invoked)
#371 Renamed IInterceptionSink to IFakeCallProcessor, ILazyInterceptionSinkProvider to IFakeCallProcessorProvider, LazyFakeManagerProvider to FakeManagerProvider
#371 Extended the serialization scenarios in the integration tests and made LazyFakeManagerProvider serializable as it's now necessary
