about page design updates

Per @jehlers

- Easy to read
  - [x] Text should be vertically centered next to the giant computer (at least pushed down a lot!)
- Easy to navigate
  - [x] "Learn more in Regulation History" should be an anchor link down to the history section (smaller text and blue)
  - [x] 30px-ish padding between text and "animated gif"
- Related information
  - [x] "Limited section-by-section available. Check the Federal Register for more." should have a line-height of about half of what it is now 
  - [x] AND should be closer to the text above it (so it seems more related)
- Regulation Timeline
  - [x] icon for reg timeline should be a tiny bit bigger... looks small and puny compared to #s 
  - [x] compare image should be closer to compare explanation 
- Overall
  - [x] Needs WAY more padding under each main title (30-60px)
  - [x] More padding above and below each section (same as whatever you do above)
