Path and variable fixes

Status: **Ready to merge**

Reviewers: **@jeffkamo @ry5n @kpeatt**

## Changes
- Fixed some variable names to be consistent with the new variable naming convention
- Fixed path issue in fixture.scss

Was the original path broken? I thought I had configured the Sass import path such that bower_components would always be found by name. If not, can we fix it so that it works? In general, I don’t like card-coded relative paths.

That specific change could be made in a follow-up if this is indeed broken right now; variable name fixes should go in ASAP.
