Background uploader

[tibfox]

We need a background uploader instead uploading in the main app. That wa the user can close the app without any problems. Also this would be a good first step for an youtube autosync. I dont know if we can create such a background service without creating a new app for itself. But I think we could create a separate app which the user can install. DTubeGo can detect that this app is installed (by checking some config file or whatever) and forward the upload instructions to this app somehow.

More reearch needed for this.
