Fixed: Quitting a standalone and saving open stacks

[Bill Vlahos]

I was able to make it work by adding an additional quit statement  
after the repeat loops.

on shutdownRequest
   put the openStacks into vOpenStacks
   filter vOpenStacks with "*.ifw"
   if the number of lines in vOpenStacks > 0 then
     repeat for each line tLine in vOpenStacks
       close stack tLine
     end repeat
     quit -- this is needed to also quit the standalone in Windows
   end if
   pass shutdownRequest
end shutdownRequest

So the extra Quit simply makes the standalone go through the filtered  
openStacks again which is very fast because there aren't any more open.

Thanks to Sarah, Ken, and Trevor for help with this.
