Modules with Long Names break formatting

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

Long module names throw off module list formatting. If you expand out the width of the terminal to the longest name, everything goes back to normal. Unfortunately this only happens for me at about 1500 pixels.

I'd suggest a truncation strategy such as `...` or something if the name gets too long.

###### Steps to reproduce the problem

Include a module with a long name. I think Webpack Dedupe is the culprit here, it creates modules that appear to be links to other modules such as `fpjs/lib/containsNode.js|/`

###### More Details
- What operating system are you on?

OSX 10.11
- What terminal application are you using?

Terminal App
- What version of webpack-dashboard are you using?

0.1.8
- What is the output of running `echo $TERM`?

xterm-256color

Start by reproducing the module list with a long module name such as `fpjs/lib/containsNode.js|/` in webpack-dashboard 0.1.8, then locate the code that formats the terminal module list. Done means long names no longer disrupt the layout at normal terminal widths and the list remains readable without expanding the terminal.
