_os.rename() fails under Windows

[jdghub]

In feeds.py the updating of the config and database files fails under Windows because the rename of the temporary updated files to the originals fail, because the original files still exist. I assume this rename succeeds under *nix, but Windows requires a preceding _os.remove() of the existing file, which resolved the problem for me, e.g.,
_os.remove(dst_config_file)
before
_os.rename(tmpfile, dst_config_file)
