[backport] backport archivebot.py from master

- Non latin digits support introduced with
  https://gerrit.wikimedia.org/r/c/pywikibot/core/+/163213
  never worked because the variable replacements like %(counter)d
  expected an int instead of s str. This did not fail as long as
  textlib.to_local_digits returned an unchanged value if there are no
  local digits given for a language but it might be failed for those
  who have it. With 7.5 textlib.to_local_digits always return a str
  and the archivebot failed. This was fixed recently with 7.5.1.
- User should be able to decide whether to use latin or non latin digits.
  Therefore a lot for new fields were introduced like 'localcounter'
  which uses the localized number instead of the latin one. This does
  not break the further implementation due to the %d replacement
  except in rare cases if the user had it replaced by %s already.
- Restore old values for non local fields
- Remove the 7.5.1 changes
- make a sanity check in analyze_page() method for the case that the
  local fields are used with %d and show a warning in this case.

- Use a generator instead of a list of pages to process. This decreases
  memory usage a lot and also speeds up start time by giving up sorting
  all pages.
- preload the page contents
- catch KeyboardInterrupt and leave the mean loop
- add look & feel of CurrentPageBot
- print execution time finally
