Log:
[RSHELL]
* Take "DbgPrint" function from explorer-new.
* CMenuBand: Show placeholder if the band gets an empty IShellFolder. Added what I guess
is a hack, to allow CMenuDeskBar to get the submenu popup from the band.
* CMenuDeskBar: Use WM_ACTIVATE and WM_ACTIVATEAPP to detect when the menu should be
closed. Uses the hack above for the exception of showing a submenu.
