OK, are you ready for a PR ?
 @bric3, please see #221

Add BDD version of verifyZeroInteractions()
Right now my tests look like:

``` java
then(file).should().moveTo(directory);
then(log).should().warn("Moved file"));
verifyZeroInteractions(otherFile);
```

Would be great to have BDD replacement for `verifyZeroInteractions()`. Then the test would be even nicer:

``` java
then(file).should().moveTo(directory);
then(log).should().warn("Moved file"));
then(otherFile).shouldHaveZeroInteractions();
```
