Added multi-locale support and locale de-DE as an example / for my personal usage.

Does this work for anyone? It's just plays the audiobook from the beginning every time and skipping to chapter x doesn't work either.

It resumes playback of the desired audiobook and remembers the last position. Unfortunately, I can't skip forward or backward to a specific time or chapter. I'm not sure if this is due to abs-alexa-german, or if it would happen with the original version as well. @Ting3l does fast-forwarding or rewinding work for you?

ps.
The problem is that the session ends, and Alexa can't process the intents anymore.
When I call the invocations again, “skip” and “jump” work too.

Sadly I'm currently barely using the abs-alexa-integration. There seems to be a lot of hickups in it anyway.
To answer your question tho, I think this would happen with the original as well - I only added some variables and a localization, but didn't change any of the underlying code. With this PR I only aimed to give way for easy language additions.
