More Pom updates.

Fixed shading to fit common standards (mostly).

Shading scala is generally frowned upon (being that it is a pretty largely used thing), and we don't even rename it...
 - Realistically, a server admin won't download scala-library.jar from the maven repo (the only place you can find it currently).
 - Relocating it in the jar will screw with language level scala code.

 So basically, scala can't be touched.
