Implement rule to check comments against top comments from other sources

Based on the description of karma farming from this thread.

Comments

Check the content of a comment activity against a list of "top" text comments based (and retrieved from) on the submission source:

• if submission is external attempt to get comments using some scraping method:
  • [x] implement youtube api call to get top comments
  • https://www.googleapis.com/youtube/v3/commentThreads?key=${API_KEY}&textFormat=plainText&order=relevance&part=snippet&filter=snippet&videoId={VIDEO_ID}&maxResults=100
  • [ ] implement twitter api to get top replies
• if submission is reddit-based
  • check for cross-posted submissions and get top comments
  • search for other submissions with the same title and get top comments
  • allow user-defined white/blacklist for subreddits to include submissions from

For detecting a match:

• [x] use fuzzy searching with user-defined threshold for sameness
• [x] allow user-defined minimum character count

Submissions

• [x] Do a reddit search for submission title and use fuzzy searching with user-defined threshold for sameness

  • [x] Allow user-defined white/blacklist for subreddits search

    ---

• [x] cache retrieved comments using a unique id based on submission source

• Restricting subreddit search

  • Define subreddits to search with this syntax: https://reddit.com/r/mealtimevideos+videos/search?q=${QUERY}&restrict_sr=1
  • For blacklist just filter subreddits out of returned results

• Search by submission url

  • Remove query string from submission url IE remove ?someQueryParam=... since reddit seems to only search by base url
  • Use url token in query to search by url IE .../search?q=url:${BASE_URL}

Implemented majority of this in 9d0e098db13cd7d29b01fd222a4a3f5a3a58670d a787e4515b2c9747c934a41bb8a3df404d9e9cd5 and 0c31bdf25e63e0d50576b04df35d3fdd5bdd9404

@OmgImAlexis I could use another set of eyes on the documentation to make sure it makes sense. Would you mind taking a look and giving any feedback you can think of?
