Add clean-up code to SetAppIdForWindow(). This is a follow-up change for r21596. It seems this change forgot calling pps->Release() and PropVariantClear(&pv). (InitPropVariantFromString() calls SHStrDupW() to create a copy of its input string, so we have to call PropVariantClear() and delete it.) To avoid an object leak and a memory leak, this change uses ScopedComPtr<IPropertyStore> to call Release() in its destructor and call PropVariantClear() to clean-up PROPVARIANT. (My JumpList class uses a class which encapsulates PROPVARIANT. We should move the class to win_util?)
