First Genomics Status cleanup PR

Start of the epic cleanup I'm attempting with genomics status:

- Move to bootstrap 3
- General redesign / improvement of user interface
- Refactoring, cleaning, standardising of Javascript where appropriate

To make this manageable, I've created `base_new.html` and `status_new.css`, so that the updated pages can work alongside those I haven't got to. This way we can atomise the pull requests and my development branch won't get too far behind the other changes.
