Title: Add file embed-video.less to help embed youtube/vimeo videos.  

This is a small bit of CSS that lets people embed youtube and vimeo videos, maintaining the aspect ratio at different sizes. Foundation has it, and many others have posted it on their blogs or on StackOverflow. Perhaps it should just be included in bootstrap to start with.

If approved, I'll add documentation.
