Subject: [PATCH] Optimize UserCache / Thread Safe
Subject: [PATCH] Async GameProfileCache saving
Because Techable keeps complaining about how this isn't thread safe,
easier to do this than replace the entire thing.
Additionally, move Saving of the User cache to be done async, incase
the user never changed the default setting for Spigot's save on stop only.
1.17: TODO does this need the synchronized blocks anymore?
