two-sided Lout output (for modern PostScript2 printers)

[Basile STARYNKEVITCH]

It seems that Lout (3.10) does not explicitly support two-sided (ie
recto&verso) printing on modern PostScript2 printers (for instance
some HP laser printers have a two-side printing option - including
hardware to print on the other side of each sheet. Of course, more RAM
is required inside the printer)

With PostScript level 2 this is coded as 

%%BeginFeature: *Duplex True
  << /Duplex true >> setpagedevice
%%EndFeature

I patched a lout produced postscript file, adding these three lines
just after @PrependGraphic file /usr/local/share/lout/include/tab.lpg 
and it works as expected.
