About: Third pass at 4.3 about page:

* Improves some of the feature descriptions.
* Uses .org CDN for images and feature video.
* Fixes an overzealous Jetpack style that adds unwanted padding.
* Uses more specific `WP_List_Table` header.
* Adds 4.3 tagline to freedoms and credit page.
* Adds infrastructure for 4.3 about video. Only the ID needs to be updated.
* Makes all strings translatable.

Props siobhan, adamsilverstein, melchoyce, ocean90, markjaquith, helen, obenland.
Fixes #32929.
