Compare TTK plurals against CLDR

[unho]

TTK sets plurals data in https://github.com/translate/translate/blob/master/translate/lang/data.py#L29-L202 but some of them might not align with CLDR: http://mlocati.github.io/cldr-to-gettext-plural-rules/

The differences can be seen here: https://github.com/WeblateOrg/language-data/blob/master/PLURALS_DIFF.md (but it's comparing more sources and more languages)

Here is reduced table listing only the differences, it also includes default Gettext rules (if they exist) and L10n guide ones:
