Show images in comments

https://wikia-inc.atlassian.net/browse/HG-430

This is temporary workaround so we can display images in comments. It parses <figure> element, gets data-params from <img> and creates new figures based on that. Clicking on images will open File page instead of lightbox.

This has to be refactored starting from modifying the API response.
Seems like we can create a component for this, right? I'm wary of creating DOM elements with jQuery or vanilla JS even, DOM in JS doesn't maintain too well.
