subscribe-by-email-default.po needs update

Hi.
Thanks for the great plugin.
Since you are about to release a new version can you please also make all strings translation ready? ex. the string "Follow" in subscribe-by-email\front\follow-button.php line 40
And update the subscribe-by-email-default.po file?

Do you have an estimation about when you will relies the next version?

Thanks in advance
Lena
