- Reworked updater: the updater now runs independently every 3h and will only send messages to the console.

- Shortened logged messages: changed the format of the logged connection-related messages; textures displayed were shortened to placeholders to reduce console spam.

- Added diagnostics command: command /sn diagnostics can be used to retrieve the plugin version, plugin configuration and Java/JVM related information for the support to easily deal with problems and errors in configuration.
