Designating where to place output fails in many cases

[SomeoneInParticular]

As the title says; more specifically:

1. If you want to place the output in a directory relative to the current directory (i.e. ../output/publications.docx) it will fail, throwing "ValueError: too many values to unpack"
2. If you try to have it place output in a directory that doesn't already exist, it will fail, throwing "No such file or directory: 'testing/publications-articles.docx'"

Skimming through the problem code, most of these issues can be easily resolved by swapping from OS to PathLib2 for directory/file management (which I'm going to do anyways, because it's safer to use while also being part of Python's standard libraries). Nevertheless, wanted to make an issue for easy referencing during a pull request
