Use full path when creating new notebook

[mwcraig]

I think this fixes #72 by using the full path, rather than just the name of the notebook, when creating a new notebook.

The problem reported in #72 is that the notebook is always created in the root folder that jupyter was launched from (or at least that is where the file creation is attempted). If you are in a subfolder and the notebook does not already exist in the root folder, an error is raised, as reported in #72.

The other issue mentioned in #72 -- that sometimes the notebook launches but is connected to a copy in the root folder -- happens if you try to make the notebook in a subfolder and it also exists in the root folder. In that case openOrReveal opens up the one that exists in the root folder, though one also ends up with a copy in the working folder.

No idea if this is the right fix 😬
