Re: Use Python3 where possible

Probably no surprise, but I agree with everything Matthias said.

I *really* dislike the -3 suffix on some scripts, e.g. the especially
egregious nosetests2-3.  I wouldn't want to adopt a -2 suffix, so ultimately I
agree that the /usr/bin/foo should be shebanged with python3 and drop back to
`python -m foo` for anyone who needs Python 2.

If there are cases where that won't work, let's try to fix them, or deal with
them on a case-by-case basis.
