     Load WebKit and its dependencies manually so they come from DllDirectory

         I had to change WebKitInitializer to use malloc/free instead of
         new/delete to avoid pulling in WebKit (and its dependencies) early
         through use of fastMalloc.

         * WebKitInitializer/WebKitInitializer.cpp:
         (getStringValue): Changed to use malloc/free.
         (getInstalledWebKitDirectory): Ditto.
         (initializeWebKit): Call SetDllDirectory first, then load all of
         WebKit's dependencies manually, finally followed by WebKit itself.
         * WebKitInitializer/WebKitInitializer.vcproj: Added a new
         configuration to match our other projects.
         * WebKitInitializer/debug_internal.vsprops: Added.
