Creating room for eighteent datasets

#### Description
For the us-city census, we are debating adding one more dataset. There wasn't quite enough screen space on a 1440px wide screen though. This pull request takes 20 pixels off of the name column.

The longest city name I found was Grimsby/Cleethorpes on the [English](http://gb-city.census.okfn.org/) census. It still fits in the reduced name column.

This will also fix [Croatia's](http://hr-city.census.okfn.org/) census which is slightly off the page on a 1440px wide screen.
