Create standard way to add captions to images + embedded content

[TylerRadford]

Currently italicized text immediately following an image is styled as an image caption: .article img + em { font-size: 0.8125rem; font-weight: bold; color: #68707F; }

Sometimes we want to caption other types of embedded content (e.g. a tweet) or not use this default style. Can we create an easier way for users to apply or un-apply the style? That could be applied using Markdown in Siteleaf or basic tag such as <em class="caption">caption</em>
