Twenty Thirteen: Title in author bio is indented when avatars are disabled

[obenland]

There's a small bug when avatars are deactivated. The title in the author description is indented.

• With avatar: ​http://screencast.com/t/yUTWggnvG4kA
• No avatar, no fix: ​http://screencast.com/t/uiprS45TlLY
• No avatar, with fix: ​http://screencast.com/t/u8STvq20m

I'd also like to take the chance and do some CSS cleanup and add a better selector.

Can you check RTL also for .author-avatar?
