Log:
[SHELL32] -CRecycleBin: Factor out a new class called CRecyclerDropTarget, which will take
the data object and call SHFileOperation for its contents. Add a noisy print to show the
parameters passed in SHFileOperation and make it to always use DROPEFFECT_MOVE. Make
CDefaultContextMenu use the new drop target in order to delete a file.
