Update reddit + ig frontends, update rate limiting

Farside ratelimiting has been updated to return a 429 when a user
exceeds 1 request/sec. This should help eliminate a lot of scraping type
behavior that instance maintainers have been dealing with from Farside
lately.

Service changes:
- Teddit removed (not maintained)
- Bibliogram replaced by Proxigram
- Libreddit merged with redlib
