Change link and link hover color.
Move containers to a div one level below outside sections.

This allows me to easily apply full-width background properties
to the outside sections without any problems from the containers.
Edit the Stream's box-shadow.
Overhaul the index page.
Remove the 'section-' prefix on classes.
Move text styling to the body.
Edit primary-nav styles.
Remove unused link variables and tweak existing colors.
Add .site-footer styling and variables + 2 misc changes.

Remove the commented Selection variables.
Capitalize the body's background color value.
Set links for stream embeds and Twitter to new url.
Set the body's background color to the footers.

This is to make the entire background the footers color,
so on larger screen resolutions the footer isn't just a
bar, but instead covers all the whitespace.
Apply text-align to the site footer and use variable for hover link color.
Adjust $footer-color.
