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
Correct. The reasoning is for readability. Numbers are usually uppercase so `aa00` has a visual jump where `AA00` doesn't. And the spec has no guidance: http://dev.w3.org/csswg/css-color/#hex-notation
