Filter private subreddits from the explore tab.

Private subreddits are filtered out of the recommendations but could show
up in the rising links.
Sent messages: don't hide removed messages
Links: allow re-queuing for scrape if unsuccessful

If the scrape of a link fails for some reason, this will add a "retry
thumb" button to the link, which will re-add it to the queue to try
again. This will appear to similar people as the "nsfw" button - either
mods of the subreddit, the submitter, or the sponsor for a promoted
link.
oauth: Add an authorize.compact support.
Fix various json redirects around the site.
