[i18n] Use translations from twn for reflinks.py, pep8 changes

- msg, comment, autogen are replace through the twn system
- There is a link replaced by the %(manual)s identifier which has
  a default link to mw:Manual:Pywikibot/refLinks. If there is
  a translated version (like 'fr') please put the code into the
  localized_msg tuple.
- We have two remaining translation pages on local wikipedias.
  They are still kept in the L10N_msg but could be moved to the
  mw manual too.

- the remaining stuff are local L10N and could not be translated
  due to fallbacks or differences on other projects
