dummy(dll).obj is now created in wxWin/$D rather than wxWin/src/msw/$D

dummy(dll).obj is now created in wxWin/$D rather than wxWin/src/msw/$D
makefile.vc and makebase.vc no longer override the location of dummy(dll).obj that is specified in makevc.env
if wxWin/include/wx/msw/setup.h does not exist, setup0.h is copied to setup.h
[BASE builds]setup.h is no longer used from wxWin/include/wx, it is now used just like with makefile.vc.  setup.h is copied from wxWin/include/wx/msw into wxWin/lib/base(d)/wx and all references to setup.h now read this location
