Many commits in one commit, whoopsies.

I changed "a couple" things:
- Created a system for candidate approval rankings based on user input to interest questions
- Added link between rating and page styles
- Added box for email capture

To be done:
- Add back the name change functionality
- Update content for issues
- Maybe jazzify the styles associated with the different ratings brackets (good, back, abominable, etc.)
- Stub for Andrew's email capture
