[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. svn path=/trunk/; revision=72776
