Adding back bootstrap 3.0, as 2.3 broke home menu and several other styles, while fixing some styles.

- bootstrap.css is a custom build (fonts, colors, etc): http://getbootstrap.com/customize/?id=6582440
- Styled typeahead following the menu drop down
- Fixed @media queries to show background and splash screen
- Grid might need some adjustment since I removed the max-width on .container. We could also achieve that with a bootstrap custom build.
Merge pull request #34 from digitarald/re-bootstrap
