title: NG2 RC5: HTTP_PROVIDERS is deprecated
body: <p>So, in version RC5 of Angular2, they deprecated the <code>HTTP_PROVIDERS</code> and introduced the <code>HttpModule</code>.  For my application code, this is working fine, but I'm struggling to make the change in my Jasmine tests.</p>
  
  <p>Here's what I'm currently doing in my specs, but since HTTP_PROVIDERS is deprecated, what should I be doing now?  Is there something I need to <em>provide</em> instead of HTTP_PROVIDERS?  What is the correct way to do this in the RC5 world?</p>
  
  <pre><code>beforeEach(() =&gt; {
    reflectiveInjector = ReflectiveInjector.resolveAndCreate([
      HTTP_PROVIDERS,
      ...
    ]);
  
    //other code here...
  });
  
  it("should....", () =&gt; { ... });
  </code></pre>
