#450 Fix copying of JAR files to plugin folder

- Create SettingsMigrationService#copyFileFromResource (inspired from CustomSettings)
- Use new method to copy missing files in plugin folder from JAR
- Create YamlFileConfiguration inside NewSetting: FileConfiguration object provided by JavaPlugin#getConfig() sets default values from the JAR's config.yml :(
- Change ConsoleLogger to take logger from plugin (work in progress)
