Less spacing in Modules and Assets

> Please provide a description of the bug / issue, and provide the details below:

Since [scrolling doesn't work on Windows](https://github.com/FormidableLabs/webpack-dashboard/issues/26), not even in [Ubuntu on Windows](https://msdn.microsoft.com/en-us/commandline/wsl/about) nor Ubuntu on Ubuntu on Windows (over SSH!), it would be nice if you just took out the blank lines between the module and asset names so that we could see a bit more. I don't _really_ need to see a full list of assets, but there appears to be some wasted space here.
###### If the issue is visual, please provide screenshots here

###### Steps to reproduce the problem

Just start up webpack-dashboard. Make sure you have enough modules or assets to fill the box.
###### Please provide a gist of relevant files
