* Add option for disabling command suggestions; add config version
This commit adds an option for disabling command suggestions. If enabled, command suggestions will not be sent to the server so as to remove command freezing. This commit also adds a config version variable so users are notified when to regenerate their configs.
* Rename GeyserConfiguration.checkGeyserConfiguration()
The refactors in this commit go a bit beyond the scope of what the sound/effects branch was meant to accomplish, however most of these changes are necessary so chunk caching could be reintroduced for the standalone version. The chunk caching here allows for us to get the block ID before the block was broken, and in the future allow us to implement newer features. Chunk caching is optional (and disabled by default) as on non-Bukkit versions, it can eat up a lot of RAM with many players online.
