Migration command (for users migrating from 2.X.X versions)

Before using the migration command, create a backup of your plugin directory.

To transfer the old gamefiles to the new version, log in into the server and use the command /surfeventsmigration.
This process might be a little bit demanding, so don't just run it at any moment.

Only the events are going to be transferred.

After the migration is finished, you can remove the old gamefiles from the games directory, and also the "data" folder.
A lot of the events have new settings, so for these new entries, there is no way to "import" any new value, so their values will be the default values.

Also, some bugs were fixed:
- fixed a bug that was wiping the main config file.
- fixed a bug with the forcejoin command.
