Twitter Display Guidelines

Some of these are really annoying but let's track through it all.

 - [x] 1. Links within Tweets must show full URLs and direct to t.co links (can't show t.co links in Tweets) (#13)
 - [ ] 2. Tweet authors' avatars are correctly displayed within individual Tweets (#14)
 - [x] 3. Within individual Tweets, the @username, author name, and avatar all link to the Twitter profile (#15)
 - [x] 4. Within Tweets, @usernames are properly linked to their respective Twitter profiles (#16)
 - [x] 5. Each Tweet shown provides a timestamp and provides a permalink to the original Tweet within a timestamp (#17)
 - [x] 6. If the product displays timelines, it consistently displays a Twitter logo and links back to Twitter (#18)

Afterwards will need to be sure to do:
 - [x] Cross browser testing for any visual regressions (check kiosk mode)
