Testing

[cloewen8]

I noticed that a majority of the issues are related to being unable to install. I would like to help identify and isolate these errors (make them easier to fix).

Proposal

This repository is eligible to use Travis-CI (for free) to automate testing on a variety of operating systems. I'd just need to create an additional test alongside eslint and add a Travis configuration.

Considerations

I just have a few things for you to consider:

1. Is any other automated testing planned (so I can use the same framework)?
2. Aside from the currently supported operating systems, are there any others I should account for?
3. Instead of Travis, should I design for another integration (if any)?
4. Should I move eslint into it's own script (perhaps lint) to avoid having it run by Travis?

I would also like to make sure you are on board with this change @Hackzzila before I create a pull request.
