Cleaned up vid thumb appearance.  #2513

Fixed video-indicator css.  Instead of absolute, it's relative with a negative top margin.  Works in media_gallery too.  This positioned it for all vids, isntead of just the first.

Fixed colorbox size.  Now it wraps the video perfectly.  Video gets scaled down if height or width would be too big.

Removed extra title.  That was caused by oembed_bare.  Just plain oembed doesn't include the title.  Seems a bit backwards, but who am I to judge?

Added class to each video.  Now they have spacing and distinct borders.

Fixed scrollbars.
