Small style tweaks to the view-sort-overhaul branch

* Keep "x replies" link styles consistent with other links by removing the italic variant and changing the text to red when the thread is hovered.
* Added some spacing between the "x replies" toggle and the reply list.
* Changed the quote text to italic to break up the card text.
