Filter subreddits and users (#317)

Browse Source 
* Initial work on filtering subreddits and users

* Fix doubly-prefixed subreddit name in search alt text (e.g. r/r/pics)

* Don't set post title to "Comment" if empty - this could throw off actual posts with the title "Comment"

* Filter search results

* Fix filtering to differentiate between "this subject itself is filtered" vs "all posts on this current page have been filtered"

* Remove unnecessary check

* Clean up

* Cargo format

* Collapse comments from filtered users
