Permissions Plugin ported to 1.8

I sat down today and ported all the user data to the 1.8 server. Therefore you have now userlevels back again and can see in the chat who has which level. Since no other plugins are installed, there are no additional user rights of course.

Due to the new permissions plugin I am using now, we will have a smoother time and less work for me in the future when it comes to upgrade people to another userlevel.
