Rewrite CSS

- Bump version number
- Add fuji specific CSS classes to markup to avoid inheritance issues (id + class FTW #yolo)
- Rename default variables
- Include Hybrea as brand font
- Add nested_reset to avoid inheritance issues
- Improve float clearing and remove unnecessary CSS
- Use ems for vertical spacing (allows us to bump up font-size with a single variable change)
- Removed animations and media queries in this commit, adding them back next
Add preliminary media query to hide fuji-links back

This media query is way too generous and need tweaking
Minor CSS fixed and add default purples
Improve responsiveness to mimic blog behavior
Reset line-height to avoid cascading issues and move fuji-padding defaults into container for more freedom
Iterate on default configuration for Fuji
Update Readme
Merge pull request #4 from heroku/css-refactor

Prepare v0.1.5 with a big CSS refactor
