Fixes for smoother cross compilation;

- added parser.o to msw objects in unx.t
- made sure 'lexer.c' is included in parser.y when cross compiling wxMSW
- added optional program extention PROGRAM_EXT set by configure, so that
  makeprog.env can create .exe files
- a few additions to setup.h.in (wxUSE_OWNER_DRAWN for wxMSW, hack to fix
a clash with __WINDOWS__ define in wx/deps.h
