Add Hungarian (hu) and Dutch (nl) translations to project files

* These were removed for the 1.2.4 release because they are incomplete. For after 1.2.4 / for Snapshots we add them again.
* qt_nl is not provided by Qt, thus use the one from our qttranslations subfolder
Update translation files (lupdate)

- mainly for the two re-added translations for the new string of the new authenticator return code
- the "ban lists" to "ban list" text-change removes those translations
