2.7.2

### Added: 
- Author page uses author card in header now
- Links to author page have `rel="author"` tags and `rel="me"` tags to social links for better SEO and whatnot
- If you add a Google+ profile URL to a user, they will have their posts linked with their account.

*This is all so you can see author in your search results, via Option #2 [here](https://support.google.com/webmasters/answer/1408986?expand=option2)*

### Fixed: 
- Line breaking in search form
- Input padding on URL fields too small
- Escaping URLs in social links. I guess that could help... something
