This makes it easier for downstream projects (forks) to replace the version fetching system with their own. It is as simple as implementing an interface and overriding the default implementation of org.bukkit.UnsafeValues#getVersionFetcher() It also makes it easier for us to organize things like the version history feature. Lastly I have updated the paper implementation to check against the site API rather than against jenkins.

Subject: [PATCH] Optimize UserCache / Thread Safe
|
|
|
|
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.
