ConsoleReporter displays failure message (yet exits with status code 0) if tests are marked as pending

# Problem

The `reportRunnerResults` method on the `ConsoleReporter` computes the total number of failed specs thusly:

```javascript
proto.reportRunnerResults = proto.jasmineDone = function(runner) {
  var failed = this.executed_specs - this.passed_specs;
  // ...
}
```

Since the `executed_specs` property is incremented via a call to `specDone` (from jasmine.js) when a spec is run, the value of `failed` will be non-zero if any specs had a status not equal to `passed`. The code in jasmine-runner.js, however, passes PhantomJS a status code of 1 only if one or more specs have been marked as `failed`. This combination causes the test suite to pass (from a status code perspective) while the ConsoleReporter displays a failure message.

```javascript
if(jsApiReporter.specs) {
  jsApiReporter.specs().forEach(function(spec) {
    if(spec.status === "failed") {
      exitCode = 1;
    }
  })
}

setTimeout(function() {
  window.callPhantom({
    event: 'exit',
    exitCode: exitCode
  });
}, 1);
```


# Solution

This patch introduces a new status `skipped_or_pending` and corresponding counter that is incremented when `specDone` is called and the spec has not been marked as a success or failure. The value of `failed` consumes the value of this counter. The final message displayed to the user now communicates if any tests were `pending` or `skipped`.
