Translate all the "template labels" - the not JCR stored texts displayed on the pages visible for the website visitors.

All the other things for apps, dialogs and components should be tackled by follow-up ticket(s) when RenderableDefinition is properly i18n-ized.

— Old description —

At the very least the app labels should be translated. It looks very awkward when you open the tours app and see some strings in english and others in german.

We should demonstrate how magnolia can be translated for editors.
Create german language files for the demo components & dialogs.

There should be a user outofthebox which can be used to demonstrate this - probably provided in MGNLDEMO-30 ticket.
