Translations

Hi,

here some german translations.

```
#: ?
msgid "Select folder"
msgstr "Ordner auswählen"

#: ?
msgid "Select"
msgstr "Auswählen"
```

in the tree selection popup. There seems to be comming from the js bundle.

Another question . Why is no one using "jarn.jsi18n" or something like that . I did a lot of translations with it and it's a pretty nice way in handling translations in plone and js.
