Fix bazinga expose translation version

The BazingaExposeTranslationBundle was set to "dev-master" instead of "0.0.5", consequently the WidopPluploadBundle is hardly installable because starting version 1.* of bazinga the `ExposeTranslation` object was renamed to `Translator`.

After this PR is merged, we should tag master to 1.0 and I will do another pull request to use bazinga in its latest version.
