Rewrite in Kotlin

[blackd]

Most of the code is now in Kotlin.

• Due to incompatibility between Cloth Config and Kotlin Objects the config is still in Java.
• Mixins of course are still in Java.

New build system based on libipn-gradle.

• It's a new thing I'm developing it handles the mod loader specifics so you don't have to.
• It's Kotlin centric but it doesn't really force it on the project.
• Although it's meant for usage with libIPN based project once again it doesn't force it.
• We are now using it in its most basic form to just handle the mod loader dependencies and generate some meta data.

This release can be precursor to forge and neofroge releases.

However this will much easier if libIPN is used because of it's porting layer. And will also replace cloth config as configuration provider.
However this is something for the future.
