Build config refactoring

- Main build.gradle refactored:
    - build.gradle converted to gradle/kotlin-dsl (yes, Kotlin scripting for build config of Kscript)
    - Use plugins dsl instead of buildscript
    - Shadow JAR file name now consistent for all versions and we avoid copy to root of the project
    - Fixed project version
    - Cleaned comments
- .gitignore cleanup from useless ignores
- Default lifecycle task assemble now builds shadowJar instead of jar
- Junit 4.12 (the latest bug fix release of Junit)
