Vanilla whitelist migrator

[NobelD]

Because a function is being requested to migrate from the vanilla whitelist to this plugin a small lightweight plugin was created temporarily. Later it will be added to the base plugin.

/nwlmigrate -> Migrate from the vanilla whitelist to this plugin. /nwlimport -> Registers all players that have data saved (only uuid)

Source Code of the plugin
