community-contributions.py script erroring on some Unicode (?) input

If utilities/community-contributions.py gets certain kinds of input, a bug in either editmoin.py (the old version we're using), or in urllib, or in both, will cause this traceback:

  Traceback (most recent call last):
    File "./community-contributions.py", line 409, in <module> main()
    File "./community-contributions.py", line 401, in main

      res = map(safe_map.__getitem__, s)
  KeyError: u'\u0434'

To reproduce, simply remove the Cyrillic versions of Danilo Šegan's name ("Данило Шеган", "данило шеган") from the 'known_canonical_devs' tuple, and run the script *without* the '--dry-run' option (i.e., you have to actually invoke editmoin to get the bug to show up).

The workaround for now is that Danilo needs to be in that list anyway, and I've prepared that change in https://code.edge.launchpad.net/~kfogel/launchpad/cc-script-update-reference/+merge/12102.

However, eventually some other contributor will come along with a non-ASCII name, and we'll have this problem again.
