Initial commit
Added an example set of SCSS and imagery for testing purposes.
Removed unnecesary vendor prefixes.
Added charset declarations to the top of each SCSS file.
Fixed pathing issues to background images used in the SCSS.
Rails doesn't support the same image path if used as an inline-image or image-url.
Buttons and header updated to latest in feature-interns
Added .sass-cache to the git ignore list.
Merge branch 'master' into gh-pages
