:bug: Fixes #9 Snapshot build does not compile

I refactored the way in which the JavaFX runtime (jfxrt.jar)

These changes have been made in the Cat Hive OSS parent POM
version 3 (com.cathive:oss-parent:3).
:nail_care: Clean up authors and contributors list

Add "Zubnix" to list of contributors and add
GitHub username properties to all authors and contributors.
Remove superflous comma.
