[amarok] src: Translate more strings as string freeze is over!

the intend of string freeze is not to get nice statistics but to give
translators the chance to translate as much as possible. Adding i18n()
calls late or after the freeze contradicts that goal. ;-)

So if a string needs to be added during string freeze we still need
to add the i18n() calls, and the translators should be informed about
the new string.

Anyway, great work. ^^
