* Fix user comment post link disappearing when < 480px
* Improve user comment metadata design for mobile
* Remove formerly unused CSS class style
The prior commit introduced the usage of the `comment_subreddit` class
to identify the subreddit that the reddit user posted the comment on.
However, this class came with a legacy style within the CSS file that was
previously not used anywhere within the current day Redlib
As such this style has been removed.
