Initial refactoring of css. More to be done.

Okay so the way things are loaded is this application.css.scss includes everything, the booptstrap_and_overrides manually includes the bootstrap css at the top of the file ergo any additional changes which are made will override the initial bootstrap. I went ahead and deleted all the automatically generated css files (from Scaffolding I assume) to clean things up.

Moving forward any additional css changes should be added to the overrides stylesheet.
