WASAPI patch: exclusive mode

I have been messing a bit with WASAPI exclusive mode and i attatched a patch (modified juce WASAPI file).

It runs in both shared or exclusive mode, but its not production ready, and it currently only initialize the default buffersize.

I’d be grateful if someone with a bit more time on his hands would finish it.

Cool, I’ll take a look as soon as I get a chance - thanks!
