Tested with a build/install and run with:
"c:\Program Files (x86)\EDMarketConnector\EDMarketConnector.exe" --force-localserver-for-auth --trace

1. So now they're only defined in one place.
2. config.py does an import of them, and `from config import ...` then
chains through, so no need to update other users.
3. No need to ' # noqa E402' the killswitch/config imports now.
First pass utilising 'futurize' to do most of the work.
There's an issue with ur'\"' in l10n.py which I'm not sure how to
properly fix.
This now has errors when hitting the 'Update' button.
