This adds the aggressive mode and then applies all sugggested
changes. Also I've removed the .autopep8 file, as I think it's
better to put things in the arclint file.
To fully reproduce these changes, install autopep8 1.5 (most
recent) which catches a few more things than the linux distro
versions. Older versions are happy with the result, but they
will suggest slightly fewer changes it seems.
