Czech translation for 2.1.5

[jpretired]

Please replace the function czechTranslations() for new version 2.1.5 with content of the attached file:
2.1.5-czechtranslations.txt

Thank you, best regards.
EDIT: oops - after posting this issue I noticed that there is new release 2.1.5.1 with "updated translation".

There were many updated strings for other languages. The Czech part was already in a very good situation. I will take your input. Thank you! If there are open points, I will come back to you.

I transfered all your input. Finally there were two lines duplicated. I delted the first ones and kept the last two ones.

            '%s has no %s, and no %s recorded.' => 'Pro osobu \'%s\' chybí záznamy %s a %s.',
           
            '%s has no %s recorded.' => '%s nemá zaznamenanou skupinu %s.',
            '%s has no %s, and no %s recorded.' => 'Osoba \'%s\' nemá zaznamenané skupiny %s ani skupinu %s.',
