- Add ability to follow games on Twitch.
- Stop using redis hashes. Since individual members don't support allkeys-lru eviction, running out of memory causes a ton of slow requests. I knew I had to do this eventually. Currently my free 25 MB runs out of memory about once a week. A year ago it took months. There are other optimizations that can be done, e.g. resolving whitelisted domains only, or not resolving URLs that we know are not going to redirect.
