Fix a leak in WinLauncher shutdown

        Reviewed by Sam Weinig.

        * WinLauncher/WinLauncher.cpp:
        (_tWinMain): Replaced a delete with a Release. We can't delete the
        WebView properly since we only have a pointer to one of its
        interfaces. We also shouldn't be deleting COM objects directly anyway,
        for a number of reasons.
