Add Java Core Mods

[shartte]

Mods must ship a separate Jar-file (for example via jar-in-jar) and mark it as FMLModType: LIBRARY to make it load above the GAME layer. They then must provide an implementation of ICoreMod via the Java ServiceLoader to contribute their transformers.

This tries to avoid loading the script-engine based coremod library unless any modfile contains such coremod scripts.

[Technici4n]

We do not have generics for ITransformer yet. :P

[shartte]

@Technici4n You will notice that it did compile (yes, yes, license violation...) with FML head, so I think we do ;-)

[Technici4n]

Ah, yes we do. Didn't read why the build was failing. 😁

Good idea in any case. We can change the interface later but for now this is good enough. I also expect noticeable startup time improvements once we move the NF coremods to this.
