Overall looks good.

However, the unit tests are failing now and there is an issue with the SQL statements in the Travis build that needs to be looked into.

@philcable The Unit tests are failing. It appears to be around this line and because the unit tests.

@stonybrookweb @philcable Oops, thanks for catching that!

I just addressed this in 95ddd4a by using " around the queries with interpolated $wpdb data. I'll do a quick check across the other projects to make sure that didn't pop up elsewhere.

8ddb4e5 then removes a piece from the unit tests that was ignoring incorrect use of $wpdb->prepare() and the tests are passing.

I left the conflict with the changelog as is for now.
