Add Levy and Goldberg (2014) to the references

The entry was already in templates/references.html.ep, commented out, with
a link to the old papers.nips.cc path. It is uncommented, completed with
volume and pages, repointed at the URL that path now redirects to, and
added to the Readme as well.

Nothing in the text cites it. Whether the dot product the predictive
collocators are computed from corresponds to the shifted PMI the paper
derives for SGNS has not been checked for this position-specific variant,
so it stands as background rather than as a justification.
