Moved fake manager creation and initial configuration into the proxy generator (Part I)

This is the first part of PR #372 (we split it up into 2 PRs as mentioned there).

It solves #371 partially, namely that the default behavior is available inside the c'tor call. Therefore it also solves the bug #368 (see the `when_faking_a_class_which_calls_virtual_property_members_in_constructor` test case).
`typeOfFake` is known everywhere `LazyInterceptionSinkProvider.EnsureInitialized` is called, and could be known everywhere `LazyInterceptionSinkProvider.Fetch` and is called, if `CastleDynamicProxyGenerator.ProxyInterceptor` and `DelegateProxyGenerator.DelegateCallInterceptedEventRaiser` had `typeOfFake`. They are both private classes and it looks to me like they could easily have the type injected.
