Subject: [PATCH] build.gradle.kts rebuilt from ground up to ensure MVJ
 understands how everything connects.

Also, shadowJar plugin and task introduced to produce single JAR file with both library and all dependencies. We now get a single JAR file that can be loaded as library and contains everything the code needs.
