• Changed Maven Group ID to com.github.jengelman.gradle.plugins
• Published artifact to JCenter
• Upgraded to Gradle 1.10
• Main task renamed to be 'shadowJar' instead of 'shadow'. This was done so the task and extension namespace
  did not collide.

• Added support for class Relocation, thanks to Baron Roberts
