The most notable changes are a refactor of DataManager to make the caching system easier to tweak, and the ability to use Lua scripts that run on the Redis server to optimize certain batch operations (currently, only getServersToPlayers() uses this).
This also paves the way for me to deprecate old versions of Redis. Anything older than 2.6 is ancient, and even 2.6 is ancient, so it ends up being a net overall benefit.
@vemacs, do not change this, or I will not only revoke your access to the repo, I will also skin you alive. Using "API" methods in this context is just fine and just because it doesn't suit your fancy doesn't mean you can just change it. I am the BDFL, obey me.
