- clean DllReferenceCount, better DllMain()
- dynamically linking LookupIconIdFromDirectoryEx32 and
CreateIconFromResourceEx32 to USER32
- moved guid's instances to new file shellguid.c
- implemented ShellExecuteEx32W
- include/winuser.h - interface relevant to user32.spec
- include/wine/winuser16.h - the old 16 bit interface (internal use)
- include/winbase.h - some minor updates to keep things coherent.
- Lot of other files made to include wine/winuser16.h, which is no
longer included from windows.h
