Style Updates

Here are a bunch of updates to our style guides:

* Description is more unique to Intrepid not thoughtbot
* Add linter suggestions and config files
* Hex color code style changes
* Uppercase color letters
* Discontinue using `_factory` variables
* Discontinue avoiding bang methods
Oh, I was assuming they were for factory girl. Happy to put back if it's for the app. I was thinking if you were in a test you'd have to always say `user_factory = create(:user)`
