Log:
[SHELL32]
- SHCreateDefaultContextMenu: Since our shell folders don't pass the array of class
keys needed, populate this array right in SHCreateDefaultContextMenu. This code should
later be moved to the shell folders so as to make CDefaultContextMenu.cpp agnostic to the
kind of items it handles.
- CDefaultContextMenu: Simplify filling the menu by making use of the array of keys passed
in the DEFCONTEXTMENU struct.
