This update for hamcrest fixes the following issues:

- hamcrest was updated to version 3.0:

  * Breaking Changes:

    + From version 3.0, the jar distributed to Maven Central is now
      compiled to Java 1.8 bytecode, and is not compatible with
      previous versions of Java.
      Developers who use Java 1.7 earlier can still depend upon
      hamcrest-2.2.jar.

  * Improvements:
  
    + FileMatchersTest simplification
    + License cleanup
