os.rename() on temporary output file does not work across filesystems

[lvml]

The code at:

radiacode-tools/src/radiacode_poll.py

Line 330 in 3fee9e3

os.rename(tfn, args.outfile)

fails if the current working directory is on a different filesystem than the output file:
OSError: [Errno 18] Invalid cross-device link: '/home/somedir/tmpu0m35l74' -> '/tmp/myoutputfile.n42'

A simple fix would be to use

   shutil.move(tfn, args.outfile)

instead of os.rename().
