Complete plugin rewrite

Plugin has been completely rewritten to fully optimize it and make it so it's easier to add support for different types of server software if need arises. Versions below 2.0 are from now on considered legacy and will not be supported anymore.

Each implementation now has its own jar file, so make sure you're getting the version you want!

Configs from legacy versions are not compatible and will NOT be automatically migrated. You need to do it yourself. It's not that hard, you only need to move some stuff around to conform to the new naming. New naming has been applied to the config so there will be (hopefully) no more confusion about the options and sections. There are also safeguards that will correct you if you do get something wrong, like inputting a cubcommand into command list etc :)

A HUGE Thank You for all the people who helped to test the new version in the alpha stages and to all people supporting the development of the plugin and giving feedback.
