reactos/reactos/dll/win32/shell32/CDefaultContextMenu.cpp
Giannis Adamopoulos 99548a5a34 [SHELL32] 
- CDefViewBckgrndMenu : Add class to handle the background menu of the CDefView and handle stuff that previously were handled by CDefaultContextMenu. Let the shell folders fill their own part of the background context menu.
- CDefView: Create a CDefViewBckgrndMenu instead of a CDefaultContextMenu which was completely wrong.
- CDesktopFolder, CFSFolder: Implement returning the background context menu in CreateViewObject. Note that I am not completely sure that the callback should be adding the Properties item.
- CDefaultContextMenu: Remove code that was moved to CDefViewBckgrndMenu and try to improve the overzealous debug prints regarding the shell extensions.
