[ysb33r]

We need to do the following before releasing 0.1.4

1. Merge WIP create executable jar using jruby-main artifact #38
2. Remove support for and dependencies on shadowJar
3. Update the README with the new documentation - Explicitly state that it is a breaking change.
4. Mark the new jruby-mains as @Incubating
5. Update Spock framework to 1.0
6. Remove maven { url 'http://dl.bintray.com/rtyler/jruby' }
7. Delay the use of JrubyVersion until last possible moment (see Setting jruby.defaultVersion must happen before loading of jar plugin jruby-gradle-plugin#115)
8. FIx the hard-coded 0.2.0 in JRubyJarPlugin - https://github.com/jruby-gradle/jruby-gradle-jar-plugin/pull/38/files#diff-0db12cd653b5b3468ac21351b2bf8466R73
