Prevent cross-domain managed type sharing by appending '_Token' to all .NET classes registered by the bridge in multi-domain scenarios. By default the first domain to register with the bridge does not mangle type names. Subsequent bridge bootstraps require a token. The token can be specified in the call to ObjectiveCRuntime.Initialize() or generated automatically for each domain by calling ObjectiveCRuntime.EnableAutoDomainTokens() prior to the first bootstrap.
Native backed types must not be registered and must instead report !Class.IsMapped() && Class.Get() == null so that callers can determine available types at runtime.
