Minor styling tweaks per email

- Changed 'Recent' to 'Notable' in About page
- Removed 'First Mate' and 'Captain' from footer
- Brought down the yellow some on the opening video
(I'm not sure whether I like it better or not. I've pushed up versions
of both, so you can compare side by side.)
Old yellow: sidetracked.herokuapp.com
New browny yellow: sidetracked.herokuapp.com/alt
