Make the whole titles of birthdays localized

[l3u]

Hi :-)

Thanks a lot for your nice app!

I have a small suggestion for an improvement. I don't know how easy this would be to implement, as I only know coding C++/Qt, not Java … At the moment, a birthday's title is generated by adding "'s birthday" to the respective name. In my case, using a German locale, this would be e. g. "Tobias Leupold's Geburtstag". This is wrong, as it should be "Tobias Leupolds Geburtstag", without the apostrophe (except for names ending with "s" or "z", where only an apostrohe without the "s" would have to be appended, e. g. "Ralph Schmitz' Geburtstag").

Surely only a minor issue, but maybe something you may want to change.

Cheers, Tobias
