• Break plugin into multiple sub-plugins. ShadowBasePlugin is always applied.
  ShadowJavaPlugin and ShadowApplicationPlugin are applied in reaction to applying the java and application
  plugins respectively.
• Shadow does not applied java plugin automatically. java or groovy must be applied in conjunction with shadow.
• Moved artifact filtering to dependencies {} block underneath shadowJar. This allows better include/exclude control
  for dependencies.
• Dependencies added to the shadow configuration are automatically added to the Class-Path attribute in the manifest
  for shadowJar
• Applying application plugin and settings mainClassName automatically configures the Main-Class attribute in
  the manifest for shadowJar
• runShadow now utilizes the output of the shadowJar and executes using java -jar <shadow jar file>
• Start Scripts for shadow distribution now utilize java -jar to execute instead of placing all files on classpath
  and executing main class.
• Excluding/Including dependencies no longer includes transitive dependencies. All dependencies for inclusion/exclusion
  must be explicitly configured via a spec.
