pls update WorldTests example plugin:

Now that the Data API is reasonably stable, and the data abstractions from common have made it into the main api, a plugin should be written that shows usage of custom data. I know this kind of example would be very useful to me., and I'm sure many others would benefit as well. I think that, in general, the example should include:

• Single data (both primitive, and string-convertible)
• Multi-Data
• Everything required to make the data "work" and be serialized/peristent

(I would write it myself, but I would need some sort of example plugin to follow before I got the hang of it)

It will give a short explanation to what the project does and anything it implements (Usage of commands in WorldTest, using schedulers in SchedulerTest, etc.)

There should be a simple reference plugin that provides the permission service.

• Store permissions in hocon config
• Reload command (no ingame permission modification)
• Basic group support?
• Dimension and World context (or combination of both)

It would be great to have a "boilerplate" for plugins with a separate API.
The plugin should contain a simple service interface and an implementation. This way we can also show how to register and use custom services.

Structure:

• Project: notification
  • Subproject: notification-api
    • Interface: NotificationService
  • Subproject: notification-sponge
    • Class: NotificationPlugin
    • Class: SimpleNotificationService

The plugin displays a notification to players when they login.

They can mark the notification as read with /notification clear.
Admins can set the notification with /notification set <msg> or delete it with /notification delete.
The command uses the SimpleDispatcher class for subcommands.

Other plugins can get the NotificationService from the service manager and modify the notification. Plugins can also set an expiration date for the notification.

For simplicity, the notification is not persistent when the server restarts.

Right now I don't have the time to work on this, that's why I created this issue as a reminder. If you want to work on this, go ahead...
