Debug log listener when debugging cake from VS (attached process)

I am currently trying to attach a debugger to the Cake process in order to debug an add-in. I've chosen the full VS approach (since that's where I am developing the extension), but the logging is not being written to the output window of VS which is not as convenient as it could be.

I think it should be fairly easy to redirect logging to the output window *if* a debugger is attached. At first I thought to use `Debug.WriteLine`, but since Cake is not being built in debug mode, this will probably not work.

I'll try to think of some other ways, but for now I just want to open this ticket so we can discuss this together.

The issue does not name a file, test, or logging entry point. Start by tracing Cake's existing logging while attached to a Visual Studio debugger and evaluate how debugger-aware output could work; done means Cake logs appear in Visual Studio's Output window without requiring a debug build.
