Fixed the update feature (hopefully for the last time).

Quellcode durchsuchen 
The problem is that ProtocolLib is using a different naming convention 
where each release has a version suffix. So, while we can't use the
update folder to replace the JAR file, it's also not needed since
we can simply add it to the plugins directory directly and remove
the old version on shutdown.
