    Makefile-newvs: some .vcxproj.filters files are in builddir, some in srcdir
    
    Without this change, out-of-tree distcheck doesn't get very far.
    
    Similarly, allow *.vcxproj, *.props to be in either the builddir or
    the srcdir.
    
    Finally, since I'm touching these lines anyway, eliminate some
    useless uses of cat: "cat x | sed 's/foo/bar/' > y" is
    equivalent to "sed 's/foo/bar/' < x > y".
