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.
@kenkouot: apart from what @hakubo said - this code doesn't touch the DOM.

From what I understand jQuery creates elements "on the side" and then returns HTML string which is handled by Ember itself.
