Title: Add adjusted-cosine and Jaccard distance metrics to kNN recommender

Hi there,

Thanks for writing mrec! I'm using it here at Flipboard to baseline some potential recommenders. In doing that, I needed to check a couple of additional metrics – Jaccard and adjusted-cosine similarity – which weren't currently supported.

This pull request adds those metrics and updates the documentation to mention them.
