TODO:
* TODO Features:
-> Load Twitch.tv clips
-> Viewing a post's media should mark the link as "visited" (purple).
-> Clicking "X comments" loads comments in a dropdown
-> Posts that link to other posts shows comments in dropdown, see https://www.reddit.com/r/SubredditSimMeta/ for examples
-> UX Overhaul: Hovering a post has /large/ buttons to 1. Expand the content, 2. Expand the comments, 3. Hide this post, 4. Filter the subreddit
-> Media overhaul: Don't rely on max-height, allow resizing of images
-> Customizable UI colors. Or at least different themes.
-> CSS overhaul: Define colors as variables. call GM_addStyle for different styles.
