* Merge all gradle files
The specific build files are now much smaller, so a single one is mostly acceptable now.
Also updates Gradle to 5.6.3
* Disable the Mixin annotation processor when importing this project into IntelliJ since it should only be needed to generate refmaps on an actual build.
* Removed Sonarqube and JaCoCo plugins.

Provides a new configuration `mods` which can be used on Maven Artifacts. That way, we can install them without affecting them on runtime (less load time)
Put the optional tasks into `optional.gradle` where a install task is just a copy task and the deinstall task a delete task
Added maven local to the repositories, if for some reason somebody uses a local maven
