Merge pull request #56 from AtomicBlom/save-command

Server-side Save Command
Fixed the config property descriptions.
Added @AtomicBlom to the credits/contributors.
Removed the canCommandSenderUseCommand override to actually make use of the permission levels.
Localization update.
Made the mod optional on both sides.
Updated the core.
Set blocks individually instead of setting them in bulk.
Extracted chunk-wise code in preparation for scheduled/delayed schematic creation.
Simplified the proxy classes.
Added queued schematic saving.
This will prevent the client/server from freezing when saving a schematic.
