Split fetch methode into multiple files if desired

[kowall116]

Adding a filename string to a methode story object will pipe the text and images into that file. Having multiple stories with the same filename will pipe those all into the same file.

Usage:

    ...
    "methode": {
        "story": [
            {
                "path": "path/to/xml"
            },
            {
                "path": "path/to/another/xml",
                "filename": "name-of-hbs-file"
            }
        ]
    }
