[UI] .status-comments doesn't need a fixed height

[trwnh]

Since the image container is now using a block model (display: block), you no longer have to set an explicit height for the comments section. Disabling that rule actually makes the cards look better. For example:

URL	Before	After

Damn, I've actually been trying to accomplish the After image through alternate means; this is a way better approach.

@DeadSuperHero Blame it on Bootstrap! It's pretty straightforward and not at all confusing when the UI is written from scratch :P In the block model, everything is already a block, and containers expand to fit their contents.

Should be fixed as soon as #162 is deployed!
