Missing follow-up change in the rest of the file.

Thanks for spotting that, I messed up during the (huge) git add -p session :p

Python 3's urlopen is equivalent to urllib2.urlopen not urllib.urlopen so I recommend importing from urllib2 instead.

This should be the same as dump_ast_matchers.py i.e.:

try:
    from urllib.request import urlopen
except ImportError:
    from urllib2 import urlopen

This still isn't done.

Sorry for the noise :-/
