Badges support

[KatieMFritz]

I noticed that there was a badges.html being included in the page-header.html but the styles were never defined, and the badges weren't showing up in the component view.

• added badge support to component-category.html'
• refactored badges.html to account for the component-category.html using componentPage.status instead of page.status
• added various statuses to the three components in the Blocks and Cards component directory to test
• added some basic badge styles (should we be worried about font size/accessibility?)
• converted tabs to spaces on style-guide.scss, hopefully not messing things up too badly 😬

Hey @KatieMFritz! Thanks so much for the tremendous contribution. Thanks for the eagle-eye on noticing the badges in the first place, and for bringing them to life. The project the Style Guide Guide was born from made ample use of the badges, but I clearly didn't get around to translating them into this project. Thanks again!
