Reddit plugin for YAGPDB

How the feed works

Uses the same method mee6 uses for reliable cost effective scanning of all reddit posts.

works by by manually checking 100 ids per couple of second via the /api/info.json?id=t3_id1,t3_id2 etc route.

It then updates the cursor to the highest returned post id, continuing from that next call.

I don't believe this method has any bad parts at this moment, it seems to be more than enough even at a 5 second interval, unlike the polling of /all/new this does not appear to have any limitations on old posts and also shows absolutely all posts.

Redis layout:

reddit_last_post_id id of last post processed

global_subreddit_watch:sub Type: hash Key: {{guild}}:{{watchid}} Value: SubredditWatchItem

guild_subreddit_watch:guildid Type: hash Key: {{watchid}} Value: SubredditWatchItem

watchid is a per guild increasing id for items
