title: Ignored build paths in sencha touch 2
body: <p>When i try to build my package for production the custom build path i have set up in my app.json is ignored. I got this in my buildPath:</p>
  
  <pre><code>"buildPaths": {
          "testing":    "build/testing",
          "production": "build/project/assets/www",
          "package":    "build/project/assets/www",
          "native":     "build/native",
  },
  </code></pre>
  
  <p>The thing is when i run this command in my command line:</p>
  
  <pre><code>sencha app build production
  </code></pre>
  
  <p>The commandline continues and ends without an error. But when i look into my buildpath, i only see a folder called: production. Why are these buildpaths ignored? I assume that when i set these values that my app will go into the build/project/assets/www folder. What is wrong?</p>
