[Translators] issues in source

[Thomas Bellmann]

An issue regarding syntax the translators aren't able to resolve
appears at
#: src/imap_gtk.c:566
msgid "Do you want to %s the '%s' folder?"

No matter if I translate it
msgstr "Möchten Sie den Ordner %s '%s'?"
or
msgstr "Möchten Sie den Ordner %s '%s'?"

The output I get is:
| Möchten Sie den Ordner 'abonnieren' Sent?
or
| Möchten Sie den Ordner abonnieren 'Sent'?

Translating this back into English it would be

| Do you want the folder subscribe Sent?

The expected outcome was
| Möchten Sie den Ordner 'Sent' abonnieren ?

==

Maybe a minor typo:

#: src/addrgather.c:247
msgid "address added by claws-mail"

-> All other mentions of the program are without the "-"
