all .thumbnail img now have max-width of 100% ; remove all instances of the redundant class .featured-video-thumbnail, added .thumbnail
change .entry-image to .thumbnail ; remove span wrapping image in get_video_thumbnail()
'thumb' is a reserved image size, change to 'thumb-small'
the general post/content styles were nested too deeply, making it difficult to override
adjust sizing and other aspects of thumbnails. fixes #25

thumbnails must be regenerated on live site, however
