Added Coveralls/Coverity support to CI

• https://coveralls.io/r/bkimminich/kata-tcg (currently only tcg-java is measured)
• https://scan.coverity.com/projects/2931 (currently only tcg-java is measured)

Full CI for all sample implementations

Travis triggers umbrella Gradle build which uses adapters to Node and Clojure to build all samples

Initial Build and CI

Setup build and CI for Java sample implementation

• using Gradle for building with umbrella gradle file on top level
• removed library folder as dependencies will now be resolved by Gradle
• using a Travis-CI job for continuous integration

Healing Rule in Java 8 and implementations in other languages

Changes in the original Java 8 implementation

• Introduced concept of Move to allow different Actions with a played card
• Healing Rule implemented as additional Action
• Custom Hamcrest matcher for asserting moves

Implementations in other languages

• Groovy (Basic Ruleset with simple Swing-dialog based UI)
  • Spock for testing
• Javascript (work in progress)
  • Karma + Jasmine for testing
• Clojure (work in very slow progress)

Compact Java 8 solution without any fancy extras

• ruleset completely implemented
• two different strategies for CPU players
• simple System.in based card selection for human players
• simple output via java.util.logging API

Features explicitly not implemented in this version
